SQA Higher Biology exam 2026: new paper structure, timings and a revision plan that fits

Everything you need to know about sitting the Higher Biology exam under the new single-paper format, from the structure of the paper to a timing plan you can rehearse.

01The structure (this changed)

Higher Biology no longer has two question papers. Qualifications Scotland, the body that replaced the SQA on 1 February 2026, has combined them into a single question paper.

Section 1 is multiple choice, worth 20 marks. Section 2 is restricted response and extended response, worth 80 marks. The paper totals 100 marks and lasts 2 hours 30 minutes.

The assignment is worth 20 raw marks, scaled to 25, and is written earlier in the year under controlled conditions. That gives a course total of 125 marks.

If a revision guide tells you the course is 120 marks across Paper 1 and Paper 2, it is describing the old format. The biology content did not change at all, only the container.

Exact exam dates are published in the Qualifications Scotland exam timetable each year, usually for the spring diet in May. Check the current timetable, since the date moves year to year.

02Timing that works

Section 1: 30 minutes maximum for the 20 multiple choice marks. That is proportional to their weight, and every extra minute here is stolen from the 80-mark section that decides your grade. If a question is not resolved in 60 seconds, guess, circle the number and move on. There is no negative marking, so never leave a blank.

Section 2: roughly 1 hour 45 for 80 marks, which is about 1.3 minutes per mark. Leave the last 15 minutes to revisit the circled multiple choice questions and check your extended responses.

Write those timings at the top of your answer booklet in the first minute. It takes fifteen seconds and it is the highest-return fifteen seconds in the exam.

03The order to answer in

You do not have to work front to back. A sensible approach is to do the whole paper in order but move on quickly whenever a question does not open up within thirty seconds, marking it to return to. Coming back with fresh eyes solves a surprising number of them, and it protects the marks at the end.

04A revision plan from now to the exam

Autumn term. Learn content as it is taught, and after each topic do the past paper questions on that topic only. Build the habit of marking your own work with the official marking instructions from the start.

Christmas to prelim. First full pass of the whole course. One topic paper a week plus one full paper open book. Fix content gaps here, because after February there is no time to learn things from scratch.

February to Easter. The assignment, done properly, plus a full paper every fortnight to time. Start the running log of lost marks by reason.

Easter to May. One full paper a week, all to time, all marked with the marking instructions. Rework old wrong questions rather than only doing new papers. In the final two weeks, stop starting new topics.

05The week before

Redo the most recent past paper you have already done. Re-read your log of lost marks, not your notes. Rewrite the extended responses you have previously got wrong. Sleep properly, because Paper 2 is a long paper and concentration in the final forty minutes decides several marks.

06On the day

Read every question twice, and underline the command word. Check units on every calculation. If a question gives you data, use the data in your answer, quoting a value where possible. Leave nothing blank.
