7 days is a really short time. What I can recommend is that you continue learning theory for the next 2-3 days and then do tests preferably one test in the morning and one in the afternoon. Still I am afraid that you need at least 3-4 weeks of work in order to achieve your desired score. Anyway - I keep my fingers crossed!

Thanks Kasia.

For now I am just focusing on strengthening my understanding on the basics of sentence correction and investing on practice test. DO you think that I should re visit the fundamentals on RC & CR ?

you would want to consider e-gmat's SC course.. m in no way affiliated to the company but have read rave reviews ..

Dude my Few cents.

I am not sure whats your week area. ( CR, SC or RC). But still, My suggestion is -


First, If you are scoring in 630 range. you must be getting atleast 15 question wrong. So decide your strategy regarding which questions you want to skip.


Second, Focus on your weak areas and read some good material

In my opinion RC and CR are more or less same

To Brush up CR and RC Try these books
1) power score CR 2) Kaplan 800 3) Kaplan basic tutorial software (to prepare RC and CR strategy).



For SC
Kaplan 800 can be good option in this short period

Remember by correctly attempting few hard questions and managing time on CAT, you can easily take the score atleast by 20-30 points.
