Introduction
IB Chemistry is widely regarded as one of the most demanding IB subjects — not just because of the content, but because of how the exams are scheduled.
In May 2026, IB Chemistry papers are placed during a period where many students are already facing:
- Heavy science workloads
- Long exam days
- Mental fatigue from consecutive papers
Students frequently ask:
- When are the IB Chemistry exams in May 2026?
- Are HL and SL exams on the same days?
- Why does Chemistry feel harder during exams than in class?
- How should revision be planned across multiple papers?
This article explains the IB Chemistry exam schedule for May 2026, breaks down each paper, and shows how students should plan revision strategically.
IB Chemistry Exam Structure Overview
Both IB Chemistry HL and SL are assessed using multiple papers spread across the exam period.
The structure is:
- Paper 1: Short-answer and data-based questions
- Paper 2: Extended response and structured questions
- Paper 3: HL only, focusing on practical and option-based questions
Each paper tests different skills, which is why timing and pacing matter as much as content.
IB Chemistry Exam Dates for May 2026
Paper 1 (HL & SL)
Paper 1 for IB Chemistry is scheduled during Week 4 of the May 2026 exam session.
Paper 1:
- Requires rapid recall
- Tests understanding of concepts and data
- Is vulnerable to careless mistakes caused by fatigue
Because this paper often follows a demanding Week 3, students must be careful not to underestimate it.
Paper 2 (HL & SL)
Paper 2 takes place shortly after Paper 1, also during Week 4.
Paper 2:
- Requires clear, structured explanations
- Tests multi-step problem-solving
- Demands sustained focus over a long period
For many students, this is the most challenging Chemistry paper, especially late in the exam period.
Why IB Chemistry Feels So Difficult During Exams
Chemistry exams combine:
- Mathematical problem-solving
- Conceptual understanding
- Precise scientific language
When exams are taken late in the exam period, students often struggle not because they lack knowledge, but because fatigue reduces accuracy.
Chemistry punishes careless errors more than many other subjects.
Common Chemistry Scheduling Mistakes
Students frequently:
- Revise Chemistry too late
- Overload Chemistry revision during busy weeks
- Ignore Paper 3 until the final days
- Treat Paper 1 as “easy marks”
These mistakes are almost always planning-related.
How to Plan IB Chemistry Revision Around the Exam Schedule
Effective Chemistry revision should:
- Cover core content well before Week 4
- Include regular calculation and data practice
- Shift to exam-style questions closer to exams
- Reduce intensity slightly before long papers
Chemistry rewards consistency and precision, not last-minute cramming.
Using the RevisionDojo Study Planner for IB Chemistry
The RevisionDojo Study Planner helps Chemistry students manage one of the most common problems: overloading late exam weeks.
Using the planner, you can:
- Schedule Chemistry revision earlier in the cycle
- Balance Chemistry with other science subjects

Good Chemistry results come from structure, not stress.
Why Chemistry Performance Often Drops in Final Exams
Teachers consistently observe that:
- Students rush calculations
- Explanations become unclear
- Small errors accumulate
These issues are rarely due to lack of understanding — they are due to fatigue and poor pacing.

Frequently Asked Questions (FAQ)
When are IB Chemistry exams in May 2026?
IB Chemistry exams take place mainly in Week 4 of the May 2026 exam session, with HL students sitting an additional Paper 3.
Are Chemistry HL and SL exams on the same days?
Yes. HL and SL students sit Papers 1 and 2 on the same days, with HL students completing Paper 3 separately.
Which IB Chemistry paper is the hardest?
For many students, Paper 2 is the hardest due to its length, complexity, and placement late in the exam period.
Is IB Chemistry mostly calculations?
No. Chemistry requires a balance of conceptual understanding, calculations, and clear written explanations.
When should I start revising IB Chemistry for May 2026?
Ideally 10–12 weeks before exams, with structured planning that spreads revision evenly rather than cramming late.
