How can I manage my time ?

Firstly you must allocate your time - it is 1.8 minutes per mark and so you should spend no more than 72 minutes on Section A, and in section B 18 minutes for 10 mark questions and 27 minutes for 15 mark questions. You will not finish every part of every question, but that does not matter - it is better to have all questions part finished than only some questions fully finished and some not attempted. You are aiming for 50% on every question. In Section A, again you are aiming for 50%. So you should look for the short / easy questions first, before you spend time on the longer ones. Any you either cannot answer or do not have time to answer then you must guess. In Section B calculation parts, the marks are for the workings, not for the final answer. It doesn't matter if you don't finish - you are aiming for 50% then you have passed. For the written parts, you must always write something. Even if it is something you do not know much about, anything sensible is likely to get a mark and just one mark is everything if you would otherwise fail on 49%.

One of the best ways to manage your time i believe begins before the exam by practicing as much past papers as possible. When you do that you develop a routine and minimize the time you take in the exam wondering where to begin. and as John says use the clock stick to the time for each question.

You are welcome :-)
