Use your strongest arguments first. One idea per paragraph. Leave space throughout to add thoughts later. Be aware of the time. Narrow down choices.
First thought is usually best.
Watch out for generalisations. If you struggle with multi-choice questions, cover the answers, write your own answer to the question, and then match it to choices given. If your mind goes blank, move on quickly. Have relevant sections marked. You still have limited time so be as prepared as in a normal exam and use texts to reinforce your argument rather than relying on them.
