Hey! Umm I don't really know the GPA requirement because I had 3.5+ at the time I applied.
For Merit Scholarship I think you must be 3.5+ or be in the top 5
For Need based scholarship I think you will be preferred if you have a good GPA but I'm not sure it's that important.
When I applied, they took students into a conference room one by one and asked them about their financial conditions, etc. to make sure they were really needy. The form also required a lot of background information. Most of my friends got the scholarship % depending on how needy they were.
If your friend is in 5th semester I'm sure he can just ask someone from his batch about this.. that would be wiser because I'm only in my 2nd sem
