I'm not sure if you have any specific career goals. If that's the case, it may be better to take a semester to study more options, take the GMAT and start a much better programme next year.
Regarding this, I found that some schools have Jan intake but I will have to get a very good score in GMAT in a matter of 2 months and their fee structure is quite high as well.
And the fact that getting an offer is not going to be easy and I will not have backup options is not assuring.
Will this not be a very risky option?
