I know gmatclub has lot of awesome material,but i find it difficult to study online,so i was looking for books,if there are any.
I would try to get used to studying on the computer or at least answering questions on the computer. While it may be difficult at first, you need to remember that the exam is on a computer screen and thus you won't be able to underline in RC, cross out stuff in SC, etc...
I definitely think it would be beneficial to follow Rich's advice as you want to simulate the testing environment for your practice CATs and you definitely want to do it for any practice questions.
GMATPrep is a great tool (exam pack and question pack 1 are great additional resources) that allows you to filter based on difficulty of questions so I would definitely make the investment in that. GMAC has books besides the OG (they have verbal and quant review as well) that will have some difficult questions at the end. All of the GMAC books come with the online tool that allows you to design exams with only hard questions if that is what you prefer.
The
MGMAT Advanced Quant book is great because it does not focus only on questions. It also teaches you tactics and other methodologies that will help you tackle the higher difficulty quant problems.
In terms of Verbal there are a ton of good SC problems on GMAT Club but you may also want to sign up for some CATs with either Veritas or
MGMAT. With Veritas I believe you then get access to their entire question bank (not all 700 level questions but still pretty decent and difficult). With
MGMAT I know that you can purchase access to their question bank. The
MGMAT SC book is very good but doesn't really have many questions. The OG Verbal Review has about 100 "hard" (their classification) verbal questions which you may want to look into.
I think the most important aspect is making your study time effective. Do all of the questions on a computer with the work on either a notebook (so you can reference at a later date) or the yellow erasable pad that you will have on test day. Find your weaknesses and do whatever it takes to turn them into strengths. If you can narrow down a topic and subtopic and then drill it into your head, you wont make the same mistake on test day, and that is all you can truly hope for.
