I chose this video because I have trouble studying and actually retaining what I am studying. By choosing this video, I am also helping myself by picking up a few new tips and tricks. The technique that is taught in this video is space repetition. It works along side the space effect, our brains can better comprehend, connect, and recall things when you space out the information it receives. With this technique it is actually possible to put in less study hours overall but you still memorize and retain the information. One of the most important parts of studying is forgetting, since we have to work hard to retrieve it, we are less likely to forget it. Our brain is compared to a muscle, because forgetting allows your brain to build.

I chose this video because it corresponds with my other choices. It also seems like a good way for me to start studying in my accounting class, with all of the terms there are. Flashcards promote active recall, the process involves actively retrieving memories out of your brain. One of the tips the video is to make your own flashcards because it is important to intake the information and fumble around with it to make it your own. Add pictures to your card to mix around with the words, and to give you a relevant image to imagine when retrieving the information later on. Create a mnemonic device to remember the information with a simple easy to remember phrase to help recall the information. While study the cards say your answer out loud and learn first before reviewing. All of these tips will play hand in hand in effectively studying.

I chose this article because it is the article that correlates with "The most powerful way to remember what you study" video. It has a bit more detail than the video. I also linked it because I learn better by reading, so when I read this I retained more because I could read and comprehend at my own pace.

4. Spaced Repetition App Recommendations

I'll just say what we're all thinking: studying takes too much time.

There are only 24 hours in a day, and naturally you'd like to use as many of them as possible for sleeping and, I don't know, drawing pictures of robot bears or something. To achieve that goal, you need to find a method that lets you spend less time studying while retaining the same amount of information.

Here's the solution: space out your studying. By introducing time intervals between study sessions, you can remember more - even if you spend fewer actual hours studying.

This is called spaced repetition, and it may be the most powerful technique in existence for improving your brain's ability to recall what you study.

Today we're going to dig into why it's so powerful, and I'm going to show you how you can use it - both with paper flashcards and with apps. I'll also show you the time intervals that have been scientifically proven to help you remember the most information.

But first, let's look at the history behind this technique.

Spaced repetition leverages a memory phenomenon called the spacing effect, which describes how our brains learn more effectively when we space out our learning over time.

Here's how Pierce J. Howard, the author of my least favorite book to haul into coffee shops - The Owner's Manual for the Brain - explains it:

"Work involving higher mental functions, such as analysis and synthesis, needs to be spaced out to allow new neural connections to solidify. New learning drives out old learning when insufficient time intervenes."

You can think of learning as being kind of like building a brick wall; if you stack the bricks up too quickly without letting the mortar between each layer solidify, you're not going to end up with a very good wall. Spacing our your learning allows that "mental mortar" time to dry.

In fact, any kind of information benefits from this kind of spaced practice - which is something that we've known since the the birth of memory science over a 130 years ago.

Back in the late 1880's, a psychologist named Hermann Ebbinghaus became the first to systematically tackle the analysis of memory, and he did this by spending years memorizing lists of nonsensical syllables that he made up.

By meticulously recording his results - how many times he studied each list, the time intervals between his study sessions, and how much he was able to remember - Ebbinghaus was able to chart the rate at which memories "decay" over time. He showed this rate of decay in a graph called the Forgetting Curve.

The Forgetting Curve was incredibly influential to the field of memory science, but it's also a bit misleading. It bolsters the idea that memories simply fade away over time. In fact, the truth is a bit more complicated.

For example: why do we sometimes remember mundane things - old street addresses, random conversations - that we haven't thought about for years?

A New Theory of Forgetting

In his book How We Learn, author Benedict Carey describes the new theory of disuse (what he calls the "Forget to Learn" theory), which better explains why these memories seem to stick around, even as many others seemingly go the way of the dodo.

The first principle of this theory is that memories have two different strengths - storage strength and retrieval strength.

Storage strength doesn't fade over time. Once information has been acquired and the brain deems it to have met some threshold of importance, it stays stored. Storage strength can only increase through repeated recall or use.

Retrieval strength - the ability to access the memory - does fade. It's fickle, not as voluminous as storage strength, and needs regular maintenance.

As a result, "forgetting" is an accessibility problem. The memory exists in storage, but you can't find it.

To make this theory easier to understand, I like to picture my brain as a huge library.

I've got plenty of shelf space, and when I add a new book, I can be sure that it'll stay. My library is like the Svalbard Seed Vault of books; no thieves are getting in, temperature control is on lock, and the ventilation system is patrolled by trained attack praying mantises who deal with any sneaky moths.

With a library this size, though, the catalog needs lots of care and maintenance to stay useful. Over time, it'll get messy and less useful unless I keep it organized. If I don't, I won't be able to find certain books anymore.

There's no need to be overzealous about it, though. Like any maintenance process, there's a point at which I'll be "done" and can do no more good for now. Then I wait, things decay and become unorganized over time, and I come back and tidy them all up again.

This is the second principle of the "Forget to Learn" theory: The greater the drop in retrieval strength, the greater the increase in learning when the memory is accessed again. Here's how Carey puts it:

"Some 'breakdown' must occur for us to strengthen learning when we revisit the material. Without a little forgetting, you get no benefit from further study. It is what allows learning to build, like an exercised muscle."

Robert Bjork, one of the key contributors to the development of this theory, calls this the principle of desirable difficulty. And that brings us to the root of why spaced repetition is so powerful: using it helps you to maximize desirable difficulty - which, in turn, maximizes learning.

As it turns out, even Hermann Ebbinghaus knew this. During his period of research, he found that he could perfectly recite a list of 12 nonsense syllables by doing 68 repetitions one day, then 7 the next.

However, with only 38 repetitions spaced out over three days, he could do just as well. A larger learning period, but a huge reduction in the raw amount of time spent actually studying.

As Ebbinghaus put it:

"With any considerable number of repetitions, a suitable distribution of them over a space of time is decidedly more advantageous than the massing of them at a single time."

The Best Spaced Repetition Time Intervals

Of course, we don't just want a suitable distribution... we want the best distribution. After all, if spacing out your studying helps, there must be some optimal amount of space, right?

Piotr Wozniak - no relation to the Woz who built Apple's first computers - spent a ton of time researching this question.

He eventually integrated what he found into the first spaced repetition computer software, which he called SuperMemo. The algorithm that determines SuperMemo's intervals is quite complex, but here's a simplified, nutshell-version of some of his first optimal intervals:

First repetition: 1 day

Second repetition: 7 days

Third repetition: 16 days

Fourth repetition: 35 days

A study published in 2008 with over 1,300 subjects also attempted to answer this question, but this time with respect to a given test date. What they found is that the optimal gap between the first and second study sessions increases in relation to how far away the test is.

Benedict Carey interpreted their data in How We Learn and came up with the following optimal intervals based on different test dates:

Time to Test

First Study Gap

1 Week

1-2 Days

1 Month

1 Week

3 Months

2 Weeks

6 Months

3 Weeks

1 Year

1 Month

So if you've got a test coming up in a week, you should do your first session today, and then do the next session either tomorrow or the day after. I'd also recommend adding a 3rd session the day before the test.

It's important to know that these gaps are approximate - as with pretty much everything in brain/memory science, it's hard to make completely specific recommendations that will work for everyone. Still, these numbers are close, and you should take them into account when you're creating exam study schedules.

Now, as I mentioned a minute ago, Piotr Wozniak implemented (and improved) his algorithm in SuperMemo. In fact, there are many spaced repetition apps out there that all have complicated algorithms - all of which are being regularly tweaked to become better and better.

So why tell you about the optimal intervals at all? Well, that's because you can do spaced repetition the old-school way as well - with paper flash cards.

The Analog Spaced Repetition System

There are several ways of implementing a spaced repetition system into your flashcard studying, but one of the simplest and easiest to use is the Leitner system. Here's how it works.

First, you decide on a number of "boxes" you want to use for your system. I have "boxes" in quotes because I don't own little boxes and am just using rubber bands and labeled sticky notes instead - which actually makes the whole system more portable.

Each of your boxes represents a different study time interval. In a system with five boxes, a good set of intervals would be:

Box No.

Time Interval

Box 1

Every day

Box 2

Every other day

Box 3

Once a week

Box 4

Once bi-weekly

Box 5

Retired (study before test)

This schedule roughly follows the original algorithm developed by Piotr Wozniak, though I've made a couple of changes. First, I've stopped increasing the interval past two weeks to make the system work for realistic test preparation periods. Of course, you can always add more boxes if you want.

Second, I've introduced a "retired" box, which should hold cards that you definitely know. If you're in college, you're probably already super-busy with other things like trying to find an internship and coming up with money for textbooks, so I think it's alright to consider those cards "known" - but I still think it's a good idea to review them before a test.

Every card starts out in Box 1. When you get a card right, it graduates to the next box. If you get a card wrong, it goes all the way back to Box 1 - no matter where it was. In this way, you ensure that you're studying the material that challenges you often.

After your boxes are set up, all you need to do is create recurring events on your calendar so you'll know when to study each box. Pretty simple, right?

But, perhaps the analog lifestyle isn't for you. Well, come along my computer-loving brethren. We can't upload our consciousnesses and become robots yet, but we can at least use...

Spaced Repetition App Recommendations

The SRS (spaced repetition software) arena has a ton of contenders, including the aforementioned SuperMemo.

However, the most popular one these days is probably Anki, which I wrote about in my self-learning article.

Anki is popular for good reason; it has a huge community of people who share decks (though you'll learn better by making your own), it's insanely customizable, and there are free (with one caveat) apps for it on almost every platform, including

There's also a web client, so you can also do your studying straight from the browser.

The only caveat is that the iPhone version costs $24.99, which is most likely their way of letting people support the program since it's free everywhere else. However, if you can't afford that (it's pretty steep for an app, I know), you can still use the web version in Mobile Safari.

Creating cards is easy, and you can add pretty much whatever type of media you like to them - which is excellent, since adding pictures can help increase retention.

However, the real killer feature is the ability to rate your answers based on difficulty when you're studying. After you turn a card over, you can let the program know how difficult it was to answer.

If you got it straight-up wrong, you'll see it again during the same study session until you get it right. If you got it right, but it took a lot of work to dredge up the memory, you can tell Anki and it'll make sure you see that card sooner rather than later. By contrast, cards that were a snap to remember won't show up for a while longer.

This system of rating your answers really helps you get the most out of spaced repetition's two main benefits:

Maximizing the learning improvement through the spacing effect

Studying more efficiently by not wasting time on cards you already know really well

There are tons of alternatives to Anki, though. If you're looking for even more flashcard apps to help with your studies, check out our list of the best flashcard apps.

Doing well on an exam involves preparation, which means developing a schedule so that you can study material over time rather than the night before an exam. How can students put all those effective strategies together to develop a coherent study plan? Make a study schedule!

# data[].attributes.body
I chose this video so that I can maximize my study time and minimize my procrastination. A study schedule can help you stay on track and maximize the time you have to study. One pro tip is to remember to do your other work while following your study schedule without cramming your day so your brain is in the right frame of reference. A tip from the video is to prioritize your classes, depending on your grade, knowledge gaps, and what is worth the most points. An easy way to find free time is to write your day down in detail, so you can fill in the blanks with blocks of study time. When you are studying, don't just tell yourself that your studying, specifically tell yourself what exactly your studying that way you can get more done. Three main tips from the video are find when your more focused, the wellbeing of your body affects your brain, and make sure to ask for help if needed.
