Under CAL Curriculum, if you fail only in Project component then you need to repeat the project component again in the next semester. But you will have to pay 7k for it irrespective of whether you failed only in theory or theory, lab and project together. But chances of failing in project is very less as you need 50/100 and faculties tend to give that much even though the project isn’t good.
For any re-registered embedded course, the grading policy would be absolute.
