IB Chemistry Paper 1A is a multiple-choice examination that forms an integral part of the IB Chemistry exam for both SL and HL students. This paper assesses your understanding of the core chemistry concepts and is designed to test your theoretical knowledge and practical reasoning skills.

IB Chemistry Paper 1B includes data analysis questions on the syllabus. In fact, it is a combination of short and long answered questions.

Paper 1A and Paper 1B. While both parts test similar topics, there are notable differences in the number of questions and the depth of content covered.

Difference between Paper 1A and Paper 1B

Paper 1A and Paper 1B test different aspects of your IB Chemistry knowledge, each requiring specific skills and strategies to succeed.

• Paper 1A: This section consists of multiple-choice questions (MCQs) based on the syllabus content. There are 30 questions for SL students, and for HL students, there are 40 questions. Each question carries one mark. The main challenge here is managing your time efficiently, as you only have around 1 minute and 30 seconds per question. 
• Paper 1B: This section is focused on data-based questions, which assess your ability to interpret experimental data and apply knowledge to practical scenarios. SL Paper 1B has 25 marks, while HL Paper 1B is marked out of 35. The key to excelling here is having a solid grasp of experimental techniques, data analysis, and the ability to evaluate experimental results critically.

Both sections test different skills, but excelling in each requires a thorough understanding of the material and smart time management.

Format and Time Allocation for IB Chemistry Paper 1A & 1B

This exam is quite fast-paced, and both question booklets need to be answered in the same exam, so knowing the format and how to allocate your time is essential:

• SL students are given 1 hour and 30 minutes to complete both Paper 1A and Paper 1B, which means you’ll need to divide your time efficiently between the MCQs and data-based questions.
  
• HL students have 2 hours to complete the same sections, giving you more time per question, especially important for Paper 1B, where the data analysis is more involved.

One of our HL students in TutorsPlus, Nina, shared how our IB Chemistry tutor, Ayse, guided her to achieve excellent exam results:

“Ayse has been incredibly helpful in preparing me for my upcoming IB Chemistry exam. Her experience and thorough explanations have been invaluable. As an IB Chemistry HL student, I can wholeheartedly recommend her!”
