How can I learn continuously more than five hours?

Question

give me a best idea to concentrate on studies and paper presentation in semester exams....

Answer 1

I agree with Jan, plus you should use awarding method and schedule a fix time to study everyday. 30 mins of learning with 1 hour break is FAR BETTER than 5 hour marathon.

Answer 2

if you want to learn, after your time in the college or university, more then 5 hours a day, i think you need some (a lot of) coffee, fresh air and exercises, to stay fit enough
or you should have started earlier your learning efforts
