Guys, There is a book called IELTS & TOEFL MADE EASY ,it is a book by Indian guys.I feel this book has all the basics that you require. Just try this book it has sample essays etc graphs & tips for many things. The best part is it not expensive just around Rs 500.It is a good book to have with all the other books that you practice with.I found it very helpful.i have met a lot of people who have benefited from it & moreover I came across it by chance.There is extensive coverage on many topics.You dont have to go searching many places for information.Those interested can mention RAVI JOHN and mail to b_ghud@rediffmail.com. or 4ravijohn@gmail.com
