am not sure what "essay writing tips" you need ? If you are having trouble answering any particular question, please state that. In any case, there is a very active thread on Oxbridge both this year and last year and you will find discussions on essay topics. If it is general advice on writing essays you would be better off referring some books on how to write a bschool essay.
