Gorkahli keto, if you feel you are an older student and you have previous poor GPA from Nepal that you don't want to show, then instead of going for a 4 year degree, you might want to do a 2 year Associates of Science degree from a community college.

There are many community colleges that give an AS degree in bio-technology, information technology, computer repair, Health Information Management, etc. A 2 year degree like that can get your foot through the door.
