FOR ALL THE SUBJECTS MENTIONED BY ADNAN-THE FRIEND
1 when ever you read a book, magazine, newspaper or whatever do make notes of what ever you feel is imprtant. this helps you memorise the main points, for later elaboration.
2 Get your writing materials checked by an able professional of the subject
3 Refer to the past papers while making your preparations.
4 Expect 'mind boggling' method of asking the simple questions.
5 Be clear in answering. dont mess up the ideas.
i hope this, along with Adnan bhai's suggestions, would help all of us.
