Hello
Subhash
The first thing is don't worry or fear about the semsemter exam you will clear sure no doubt
But the criteria is please study atleast 3 modules perfectly in the particular subject and simply study other two modules as well that to which are more important and after this refer the previous year question papers and sample papers it means sometimes we can expect the repeated questions and also once you sloved previous year question papers you will have a guts to write the exam with confidence so if you follow above tips definitely you will pass
All the best
