GMAT Strategy

Hello Sir,
I am ****** from india.I have sad story about my journey with GMAT and i m lost with disappointment and broken heart:(.Sir when i was in 4th yr grad like 2011 i joined princeton review here in India and that was like Jan 2011 and then have been studying always but was ever confident and finally gave GMAT attempt in DEC 2011 and got 490 with Q43 V15.Now for my first attempt i did few mistake which i made sure i won't repeat for the second attempt.Mistakes were:
1.Iwould spend hours together only one 1 topic like i would do only SC for 15 days,then CR for 15 and then RC for 15,after which when i would look into SC questions i would get puzzled what is it like,am i seeing chemistry question (.
2.I solved only OG12 and few questions very few from 1000 question bank but ya i read MGMAT SC,MGMAT CR,but nothin for RC.
3.Very rarely gave practice tests (...

So i made sure i won't repeat them for 2nd attempt.Corrections made for 2nd attempt
1.I started solving questions from all topic everyday like 35 -40 questions all topics.I have downloaded many verbal questions from gmat club.com and have solved them.
2.I did not read any material for verbal but yes i am able to solve the questions on question banks and yes sir i have checked with mgmat or any forum and have found my reasoning quite satisfactory.
3. I gave practice tests and have scored 590-600 with MGMAT quant always 45+ and verbal 30.
4.My 2nd gmat attempmt score is 510 improved only by 20 after 3 months preparation:(((((..


Now Sir i need advice on where em i making mistake. i want to score 750,i know thats beyond my view ,but i wanna blast this exam very badly but i dnt know where do i start from..i will list out my problems sir please provide with me ur valuable advice:

1.Every exam set by an examiner follows pattern for the questions they prepare and so even is GMAT.Here the experts prepare there questions based on certains rules for SC those rules i know them and when i see question i am able to solve it by narrowing it down to two and y the other is wrong .It happens in practice question bank i solve many questions but in exam hall i don't know y but my head is so heavy that i forget why em i there in the exam hall. I simply don't understand the question and i get tensed as soon as i see verbal.

2.I have decided to start reading for SC from basics and i was thinking about online courses are they suggestible or should i start with SCGRAIL OR MGMAT SC read every line from basic.But sir i know the rules how does it make difference reading them again , i have to apply them , i do apply them and i get practice questions correct but ya if i give break i for the concepts again i revise and then i m able to solve again.


3.Sir CR AND RC these two r my biggest enemies i have worked hard on them and have solve 25 questions everyday and have seen improvement in my performance ,but again sir in exam hall i forget the rules for them ,as they r more than 3 lines question every time i read 4th line i forget 1st line em like what is happening,but at home i make notes and i take time and solve each question for like 2mins for rc and cr.And yes sir for CR i have read princeton CR and have not read any book for RC but ya have read post on RC at GMATCLUB and have followed it yes seen improvement in practice.


4.Quant sir this area also i dnt know how to improve i need 50 because i was Math topper at every place i have been and my subject is good ,then why em i struggling i don't struggle in MGMAT quant which student review as tough quant section.


5.On my father''s suggestion i have started jogging everyday and em attending yoga classes from today and have decided will only have healthy food.




1.Please tell me should i start preparation again from basics???
2.What books should i start with??
3.How many hours should i study and how many questions should i solve???(Yes i have read on other posts that quantity!=quality ,yes i will review them but still how many in each topic the maximum number plz)
4.Weekends i will give my exam or should it be 15 days??You know sir giving exam I'm very scared i will score very less but ya when i gave attempt 590 boost me because 490 was my 1st attempt score .
5.Should i sign up with online verbal session i have seen egmat has good reviews for non native speakers but sir plz i don't want to waste money if I'm capable,so plz u think its gonna help,my friend says if visual is how i learn then go for them,but I'm not bad student sir i work hard and i 8.3 on 10 my graduation score.

6.If u don't mind sir please give me time table sir please please i would be thankful to u all my life ...pleaseeeeeeee!!!I wanna prove the world em not so dumb so pleaseeeeeee:((!!!



Sir,plz ur suggestion would be very valuable to me and appreciate it ,THANKS in advance sir.
