Hi
sangramjk,
First of all, Welcome to GMATClub.
Since you are beginning with preparation after 7 years, I would recommend you to go the following things:
1. Download the GMATPrep software and take one of two free tests you get. You will find this in mba.com.
Once you have a preliminary score, the experts in the forum will be able to give you a clear path
as to how you should proceed.
2. Once, you begin with the preparation for GMAT, it makes sense to clear your concepts for every topic
and follow it up with some practice. To build your concepts, you could use Manhattan Guides/Math Book by GMATClub.
For SC, I will second
Inten21 to use the
eGmat to build your concepts.
There is no easy route to achieving a high accuracy in CR and RC, except extensive pratice.
You could use the PowerScore CR bible in order to get a basic understanding of how the CR section works.
For RC this link is very beneficial:

Also, Follow Bunuel at the Math Forum(for Quant Section)
His signature contains some awesome questions that give you the true taste of GMAT(Baker's Dozen, 12 Easy Pieces etc..)
Make sure you solve each and every question he puts up on the forum.
Last but not the least, this is a post which will benefit you immensely(with regards to choosing a good study plan)
