Is it true that IIT kanpur's curriculum is harder than other IITs?

My knowledge is limited to the Mechanical branch only as my brother was a student at IIT Kanpur. From what I heard about his experience, the curriculum is moderate, neither too heavy nor too light. He even saw many of his batchmates copying assignments and not doing one on their own throughout the 5 years. 

The mid and end-semester exams are usually from the notes. The average of the class is very low with everyone performing poorly. up getting a B in that course. There are some exceptional professors who do tough grading, but that is rare and mostly CPI isn’t affected.

Projects and term papers are supposed to be done as a group and carry a lot of weightage. But they are quite easy as one of the studious members of the group ends up doing all the work. 

In IIT Kanpur, one can easily score 7 CPI with average preparation done in 1 week for mid and end semesters while 1 or 2 days for projects/term papers. Hence I wouldn’t say the IIT Kanpur’s curriculum is harder than other IITs.
