4Why Practice Chemistry Mock Exams?
- Build familiarity with the new-syllabus Paper 1 (1A multiple-choice + 1B data) and Paper 2 formats before the real exam
- Master pacing across multiple-choice, data, calculation and extended-response questions
- Identify weak themes (the mole, bonding, energetics, kinetics, equilibrium, acids, redox, organic) to target revision
- Practise using the data booklet quickly — periodic table, constants, bond/thermo data, spectroscopy
- Learn what IB examiners reward — correct units, significant figures, state symbols and balanced equations
- Reduce exam anxiety through repeated realistic timed practice
Chemistry Exam Tips from Top Scorers
Show the working, with units
In calculations, write the formula, substitute, then give the answer to the right number of significant figures with units. Method marks survive even if the final number slips.
Balance equations and add state symbols
Equations usually need to be balanced AND carry state symbols (s, l, g, aq) for the mark. Check atoms balance on both sides before moving on.
Use the data booklet deliberately
Many marks come straight from the booklet — bond enthalpies, ΔHf values, the periodic table, IR/NMR/MS data. Know which section to turn to so you do not waste time.
Answer to the command term
"State"/"deduce" stay brief, "explain" needs reasons with "because", "discuss"/"evaluate" need a balanced judgement. Match your answer to the verb.
