I bet you are probably very excited about taking CAE exam. A great number of you think that this is very hard, don't you? But, it's not if you organise your time properly. Believe me!
First of all, you should make your study plans. For example, you should decide how long you can study, which is the best time for studying, according to your 'body-clock', in which room you are the most concentrated... On the other hand, it's very important to have some free time for relaxing, going out with your friends, walking etc.
Secondly, it would be very good if you read as much litereture in English as you can in order to have wider vocabulary and to improve your reading skills. Another thing which could be very useful is to write interesting essays about different topics.In that way you are improving your writing, and at the same time you're testing your grammar and vocabulary. Also I would recommand that you should speak in English and listen to cassettes to have better accent, but also to develop your listening and speaking skills. If i were you, I would mix all these activities, which means, I would do a bit of every task each day, so it wouldn't be boring and tiring.
On the other hand, what you should do in the final week? I suggest revising everything you have learned, but you should not exaggerate, because you could jumble all and become confused. It's very important to have a good rest a few days before the exam.
As you can see, it's not a big deal to organise your studies effectively, isn't it?
