You have already gone through past papers; now you should identify the questions repeating most during the last 10 years and then cover the topics related to those repeated questions.

Only three months left in CE-2011 and it is not easy to cover all of those repeating questions; therefore, you should select those questions you think easy for you.

I think this is the best approach in such short span of time.

Regards
