5.0 CGPA. Is it possible? What that means is that a student in whatever institution he comes from has straight A-grades right from his first to his final year? This hasn't been achieved in nigeria even in the world. The only person heard to do this was a nigerian who broke the record in russia: victor olalusi. Guys do you think it is a futile dream to want such an achievement or is it possible in nigeria which has institutions with bad-belle lecturer? If its possible, what can be don't to get this impossible feat?

5.00 is very possible in private universities where you dont have destiny killer lecturer,the worst is state universities where the abound

My school is a state uni and I've seen someone got 4.8 and heard someone got 5.0 two times in a row.... Its so very possible

the op said cumulative ie from first year to final year not semester by semester

The bolded is false.
The USA has a 4.0 grading system and lots of people have graduated with perfect GPA s.

To answer your question:

It is a good feeling to get good grades, and get A's in all your classes, but it is definitely not a reason to go crazy. If you can take your classes, and get good grades because you actually learned the material, and you had a good time doing it, then yes it is worth it, it is a very good feeling.
Your GPA is not a measure of your intelligence. It is not a measure of how good you are, it is not a perfect indication of how good a professional you'll be once you start working. I know many people who are incredibly smart, but who struggled in a few courses and did not get perfect grades. I also know people that try to manipulate the system, taking the minimum amount of classes, waiting for the "easy" professor, and that actually do end up with a perfect GPA because of all this manipulation.
In general, try your hardest, take classes that interest and challenge you. No one will care about your grades a couple years after you graduate. So I would say that a perfect GPA is nice, but completely overrated.

As an addendum to my previous post, http://talk.collegeconfidential.com/harvard-university/908796-who-won-the-sophia-freund-prize-in-2009-and-before-1997.html this is a list of people that graduated with perfect GPA s from Harvard
