A close friend of mine is an alumnus of IIITM Gwalior and he was able to give me some information regarding the institute.
The curriculum for CSE at IIITM Gwalior is quite good. CSE students do not have much academic load. The only thing you need to concentrate on is focusing on problem-solving skills(like designing algorithms, etc.) through coding. You should work at least 4-6 hours per day to hone these skills online, especially during the first two years of engineering.
It is not difficult to score an 8.0 CGPA, but you need to put in your honest work. However, targeting 9.0+ CGPA can be a challenge.
