work on word equations

work on topics unsure about and cannot understand

read the textbook more before the exams

make more summary notes ands do more past papers than currently solving.will clarify doubts regularly,will also refer and read through syllabus sheet

3. naming complex polymers

4. flame tests, anion, cation test

5. neutralizing soil

I should, revise the topics I am facing trouble in, and solve specific topic based questions. use the syllabus guide to revise, make concise notes and mind maps so it will be easier to relate topics with each other, increasing my retention of more difficult topics

1. exo and endothermic reaction

2. ATP tests in theory paper

3. acid bases and salts reaction

but-1-ene and but-2-ene

(c) alcohols, including

propan‑1‑ol, propan‑2‑ol, butan‑1‑ol and

1 Describe the transition elements as metals that:

(a) have high densities

(b) have high melting points

(c) form coloured compounds

(d) often act as catalysts as elements and in

To fix these mistakes, I will thoroughly read these topics again, and solve topic wise questions. Moreover, I will make notes regarding these topics which I can easily revisit during the exam. I will also reconsider my revision techniques so that I can efficiently remember every information before the exam.

mostly metal extraction, properties and periodic table and elements. not deep or clear enough with the topics and have to read the textbook more thoroughly before referring to the syllabus to reinforce. also went wrong with empirical formula calculations, will have to solve practice questions and topical papers. some of the theory in organic chemistry is also quite unclear for which I will refer to the syllabus.

# data[].attributes.body
titration, extraction of metals and such. Monomers 60/40 not good for polymers. Should study terms. Keywords like state, define or cramming aren't good so should focus like that. Monomers like alkenes should be better.

2.)enthalpy change diagram

3)flame test

4) precipitate
