Folks, I'm just listing down some books that I followed for my preparations for
CAT '07. I hope some of these will serve you well too.
QA - Arun Sharma, Trishna's QA, and TIME material. In addition, I also followed a book called 'Think without ink' to build speed. (Please note that my strategy was to completely ignore Permutations and Combinations, but I don't recommend that course of action. I suggest that you try and focus on strong areas, but also build on weaker ones, instead of ignoring them completely.)
VA/RC - Arun Sharma, Norman Lewis' books, and TIME material. I strongly advise you to not mug up word lists. They don't work. But, books like Norman Lewis' build contextual vocabulary. Also, sign up for
Dictionary and Thesaurus - Merriam-Webster Online's 'word of a day'. It is quite good, sometimes. Then, to build reading speed, there's a book called 'How to Read Better and Faster'. It might click for you too. To foolproof your grammar, there's nothing better than Wren and Martin's book.
Tip for para jumbles: Visit the Hindu or the Economist online. Copy some random article, and print out a few lines from a para, without reading it. Cut the paper so that the lines are in random order. Arrange them in sequence, and compare with the original. It'll give you a nice perspective, on your approach, and help you iron out any flaws.
DI/Reasoning - Arun Sharma, TIME material, and random GMAT questions. I suggest that you try solving questions of particular types, like network problems, truth-lie and stuff, and design your own customised approach. Trust me, it speeds up things a lot.
Also, one should do some extra reading, once in a while, to build speed/patience/interest. I don't mean read Franz Kafka, or Ayn Rand. Read contemporay fiction - Sheldon, Archer, Maclean etc. But, DON'T read passively. Be an active reader. That means, don't just read, and forget. Try to build a connection with the characters, just think about them, absorb the ambience of the book. (Reading magazines and newspapers does NOT count as extra reading.)
In addition, to boost your morale, watch some inspiring movies like Miracle, Goal (The English one), Remember the Titans, Glory Road etc. Watching underdogs triumph should give you a high. I watch such a movie before every big day in my life, and yeah, it works!
All the best! I don't say that my tips WILL work, but I hope they do, and you folks make it to the best b-schools in the country. Even if you don't, doesn't matter. As long as you try, and give it more than 100%, you'll always be heroes. Cheers!
