Is 7.56 a good grade point in the 1st semester MAKAUT exam to get a good job?

 A 7.56 CGPA is a decent score but its value depends on what your career goals and future prospects are. 

If you are looking for a job in the usual software companies, then 7.5 is a pretty decent score. But to stay on the safer side, try getting an 8.0 aggregate when it comes to DGPA. An 8.25 DGPA means 75% which seems better than 68% when asked in the interview. 

If your goal is higher studies, you will have to prepare for GATE. Also, I will recommend you pursue a Master's only if you are planning to do a Ph.D. in the future. This is because if you end up going for a job after your Master there is no need to waste 2 years after your Bachelor's in the first place. Most companies offer equal packages to BTech and MTech students so you merely wasted 2 years of your life. 

If you are willing to do a Ph.D. but want to take some rest after the Bachelor, try to get a research fellowship. 

Ultimately it all depends on the DGPA and a 7.5 is by no means a bad score, but still getting an 8 wouldn’t hurt you. Also, try getting a few courses under your belt. This will present you as a better candidate during interviews.
