Understand Paper 1A Structure & Timing
- Paper 1A tests core Chemistry knowledge with MCQs—30 questions for SL, 40 for HL.
- Each question is worth one mark and calculators are not permitted.
- You’ll typically have 30 minutes (SL) or 60 minutes (HL)—meaning less than 1m30s per question for SL!
2. Master the Key Strategies
- Read the stem carefully: Identify exactly what the question asks before peeking at options.
- Eliminate obviously wrong answers first, narrowing down your choices.
- Watch for strong qualifiers like always, never, or only — these often indicate distractors.
- Skip and return: If unsure, note it and come back later if time allows.
- Avoid overthinking: First instincts are often correct—especially under time pressure.
3. Focus Your Subject Review
Paper 1A draws directly from the core syllabus, so double‑check:
- Atomic structure & moles
- Bonding & structure
- Reaction energetics and rates
- Stoichiometry, equilibrium, acids/bases, redox
- Organic functional groups and mechanisms (SL & HL overlap)
4. Practice with Past Papers & Flashcards
- Past papers are essential: Practice under timed conditions, review answers, and note patterns in mistakes.
