I have a 3.80 from 200 level next Semester I’m entering 300 level is it possible to increase my cgpa if I get majorly B’s and some A’s and C’s. A in my school is 80 so it’s tough. I’m in accounting I want to be in second class upper at least. Will it also be possible to get a 4.5 before I graduate

80 equals an A in your school?
That's outrageous!

If your course is a 4-year course, then 300L is arguably the hardest. Getting A's all through wouldn't be easy but it is not impossible.

Somieeeee:

you want A to be 70? or maybe 65?
secondly, I hope you have at least 3 skills that can feed you because the world is no longer about your school grades. If you like get 3 first class results, no one cares.
Finally, For your sake, I hope you are thinking of starting your own company instead of job seeking because if that is why you need all this GP, then you are f#cked.

Grades that your children cannot inherit when you die is what you're killing yourself for

Buhari that ruled and Tinubu that is ruling don't even have primary school certificate.

I want to believe you have a business running or a side hustle or skills that can fetch you some real money and not just depending on some useless papers called certificates.
