Hi Anushree9326,
From what you've stated, you're not facing any immediate application deadlines, so rushing in to take the GMAT - when you probably won't hit your score goal - sounds like something of a waste of money. There's certainly nothing wrong with taking the GMAT as scheduled, and the experience of facing the Official GMAT at the Testing Facility could be beneficial to you (in terms of better preparing you for a second attempt), but that's an expensive experience. You seem comfortable with the idea that retaking the GMAT is not a "bad thing", so I would question why you're essentially forcing that to happen when you could pay $50 and push back your Test Date (and save $200 - since you wouldn't have to repay the full $250 Test Fee).
Beyond those points, I'm concerned that you're essentially going to 'waste' the two free Official GMAC CATs by forcing them into your schedule before February 14th. In addition - the study advice, suggestions, etc. that I would give you requires a longer timeframe to implement (than the 11 days that you currently have).
You can certainly approach this process in whatever way you choose, but there's something to be said for working efficiently and not wasting time/money/energy when it isn't necessary.
GMAT assassins aren't born, they're made,
