My bachelor's degree uni doesn't practice this kind of CGPA classification.
But generally, 1st Class Upper is above 3.75. 2nd Class upper is 3.5 to 3.75.

Since this is your final year, I'm not sure how much you can bump up your CGPA since it's the average of all 4/5 years' GPAs. Just concentrate on studying and understanding so that you can apply for work later and not just for scoring -there's a max to how much you can score but no max to how much you can understand. Do your final year project well and so that you can be proud to present it later to interviewers.
