How was your Quant ability in your prep course? There could be several reasons for the 320 -- are you leaving many questions unanswered? or do you have major undiagnosed gaps in your content knowledge?

I suggest utilizing online resources like Grockit, GMATPrep, and the free CATs offered by MGMAT Prep, Veritas, Princeton, etc. to hone in on your weak Quant areas and get more comfortable using software.

I get 50% in both Quant and verbal, I do a little worse in verbal than quant, right now m just trying to work through these problems on the software. First i had a problem with time, i couldnt manage time while doing the software, but i have managed to coup with that.

Practice Practice practice. that's what it comes down to. I started out very low as well but managed to increase my score by 100 points. I focused on memorizing a lot of the Math fundamentals and techniques (exponents, divisibility rules, geometry formulas, et cetera). My math increased by 9 overall points, but I noticed I wasn't evenly allocating my studies to verbal. What I would recommend is focusing on the areas of content where you can do the most damage (score high)...with math focus on algebra, arithmetic and common decimals, fractions and percentages. Make sure you know the formulas already for Work/Rate, Average, probability, permutations/combination problems.

In regards to verbal, know your sentence correction/grammar rules (pronouns, IDIOMS!!!, lists, comparisons, et cetera) as well as your critical reasoning assumption types and question types (strengthen / weaken / assumption / evaluate / paradox).

With only 9 days left I know it can be tough and maybe it's your nerves. But try to relax. If you've been doing a lot of problems out of the book that's good. BE CONFIDENT

i have been practicing 50-90 questions everyday. I m getting alot of them wrong at this point, even though i should'nt! but i think i m going to go ahead and write the exam, do a lot more practice till the 21st. do my best! and see what my result comes out, if i completely bomb it, i'll re-write it again in february.
I need to stop panicking and stay calm.

You have to figure out why you're getting them wrong and where your area(s) of focus needs to be. Is it basic understanding of math concepts? are you struggling with what the question is really asking you to solve for?

i make stupid mistakes, i get what the questions asks for, i tend to work it right, halfway then i completely go off track, or make a silly calculation error. but when i see the answer and the explanation, it seems so easy, nothing that i dont understand!

You answered your own question...just take it one step at a time, and make sure not to slip up on easy errors. If you know the material and understand the formulas you should be all set. Just continue to study and do online practice and drills and practice exams

The GMAT is similar to track. It is not a sprint it's a marathon.
