Regarding the Student Rockstar, the Coding Challenge held every month is the jackpot.. Do well in the coding challenge and you can easily gain 1000+ points per month.. Also participate actively in the forums. Other paths to points are - upload whitepapers (One request, keep it original...), download others whitepapers and rate them , post announcements and finally, login daily not only to get points but to gain knowledge too...
All the very best for your success in the competition....
