Multiple Choice Questions
These multiple choice quizzes are designed to help students check their understanding of each section of the course.
They are arranged for biological topics at the moment rather than by syllabus section.
They are marked at the click of a button for instant student feedback & correct answers.
Multiple choice questions
Paper 1 of the exam is composed entirely of multiple choice questions.
Each question has 4 answer choices- A, B, C or D
One answer in each question is the correct answer but watch out for the "distracter". This is an answer which is partly right.
A good technique for difficult multi-choice questions is to mark the obviously wrong answers on the the question paper and then choose the best answer from the choice remaining.
Advice to students
