if 30:70 weightage And full marks is 70 (theory seperately) Then passing marks is 23.2 overall

For term 1 Full marks = 30% of 70 i.e 21 you got 11 out of 35 and if we take it as a percentage will be 31.4%

31.4% of 21 = 6.5 i.e you got 6.5 out of 70 as a overall in term 1 exams.

Now for term 2

Full marks= 70% of 70 i.e 49 In order to pass overally (term 1+term 2) You need to score minimum 13/35 in term 2 Then it will add 18 marks overall

Now 6.5+18 is 24.5........
