Hi what sort of help you are looking for ? You can visit the following link to see what we have already posted as an additional support other than books.
Please note it is difficult for anyone to answer if the question is too vague or too difficult to handle... I am afraid if you are expecting to a lecture on above there will be hardly anyone to offer that specially with the exam around the corner however if you have a question with regards to specific exan diet please post it here.
kind regards,
Aneeb
