Examination timing - First examinations May 2016


IB Higher level exams

The HL IB chemistry exam consists of three papers.

Paper 1: multiple choice - 1 hour (20% - 40 marks)

There are 40 questions and you are given 60 minutes to complete them. This works out to an average of 1 minute and 30 seconds per question. This is obviously simplistic as the questions assess different skills, some of which require very little time and some require working out.

The best approach is to read through the questions one at a time answering as you go. There is usually more than enough time to complete the paper and go back to check any questions that you had difficulty with.

Calculators are not allowed


Paper 2: structured questions - 2 hours 15 minutes (36% - 90 marks)

This paper consists of two sections, section A and section B, with a relative weighting of 40 marks and 50 marks respectively.

Section A: Answer all questions

There are 40 marks given for this section making 4/9 of the total. The overall time available is 135 minutes. This equates to 60 minutes for section A. There are usually 5 questions making 12 minutes per question.

Section B: Answer two questions from the choices given.

There are 50 marks awarded for section B making 5/9 of the total. The overall time available is 135 minutes, equating to 75 minutes for section B, or 37 minutes 30 seconds per question.

Calculators are allowed

Data booklets are provided


Paper 3: Options - 1 hour 15 minutes (24% - 45 marks)

Section A: one data-based question and several short-answer questions on experimental work.

Section B: short-answer and extended-response questions from one option

IB Standard level exams

The SL IB chemistry exam consists of three papers.

Paper 1: multiple choice - 45 minutes (20% - 30 marks)

There are 30 questions about 15 of which are common with HL. You are given 45 minutes to complete them. This works out to an average of 1 minute and 30 seconds per question.

Again this timing is simplistic, as the questions assess different skills, some of which require very little time and some require working out.

The best approach is to read through the questions one at a time answering as you go. There is usually more than enough time to complete the paper and go back to check the questions with which you had difficulty.
