Your Id suggests you must be a charming damsel from the exotic country of India. GMAT is a tough nut to crack, especially when there is no lead where to start from or how to delve into it deeper!!!
Gladly, there is lots of help around on this forum. My personal suggestion, keep away from the books for some time. The following is the best study plan I could suggest, of course, these include things I have regretfully learnt after a recent debacle.
1) Browse this forum the most. Find every interesting topic and read it. Solve and answer to questions and this will help you understand where you stand as far as typical GMAT questions are concerned. Spend a week thoroughly to first understand what you know.
2) Now you know your short-comings, what you lack with math or verbal, skills that could help you boost your score to a first degree.
3) Read Manhattan books
now, this will refresh all that you have learnt and don't remember anymore or that you have learnt while solving questions from this forum. Read the books for more than 2 weeks, thoroughly. Refer Powerscore CR
bible exclusively for CR and OG math content is sufficient for revising quant.
4) Now start an Error Log
, solve questions from all books you can get your hands on. After solving a series of questions, say 20 of each type each day, review each and every question, why you got it right and why you got it wrong. Note down any tricks and traps along with the specific example for future revision. Keep this a regular activity, for more than a month.
5) After all Manhattan, Kaplan
, Powerscore books are done, then come to OG. OG is the bible for the perfect GMAT sentence structure styling and language formats. By now, you must know specifics of approach towards each question type, all you need to learn is the exact style of questions that appear on the test.
6) All through since you start your error-log, attempt some mock tests, may be once or twice a month, keep more of them for a later date, especially the GMAT Preps to the last of your preparation.
7) When you find yourself confident, plan for a date to give the test and by now, you know exactly how to go about it already.
8) All of this will take around 4 months of committed time.
Wishing you all the very best for your test.
I am AWESOME and it's gonna be LEGENDARY!!!
