Another day a very good friend of mine asked me a very interesting Question.
It goes this way: "If my class improvement result comes in February will it affect my admissions for Fall-10?"
Well, the answer is yes and no.
First start with positive side. No because in most of Good University (Remember most not all) such as Arizona State, SUNY and so on the deadline is missed by the time. But remember there are two deadlines. One for Online applications which most University accept and another is Document recieving deadline.
If i talk about my case then the deadline for Michigan State University was March 1. But that was for Online. I send the data on 15th with the request mail to the admissions dept.
So remember to submit the online application. Which does not require your score as you can mention result waiting. Even your GRE, TOEFL score space can be left blank. The only thing important in your online application will be your SOP (Some Uni. ask for online) and Application fee and term you are interested for.
Rest can be send as soon as available.
Now the bad part of the answer. There are certain University which does not accept even documents after certain date in any case (Bold because it depends on how you convince the admissions dept.). But those are rear and most University will accept Documents in March also.
So please don't worry unless you have submitted applications.
Have a great week.
