Help for 70-270 XP exam prep

kovo

I am studyin for my 70-270 exam booked in 2 weeks. I have read through the sybex XP text book twice and have scored reasonable in the practice exams that come with the book. I have done a few practice exams from the net , including one from this site and have struggled. Any ideas on what should be the best preparation for the exam in 2 weeks time. Do i just keep reading over the text book, or keep doing practice exams, is it worth while doing the same 50 question practice exam more than once? Any help and info would be great. Any study guides i should look into? Basically all ive been studyin is 1 text book and practice tests.
