1. I recently sat an exam that is worth 60% of my overall grade, the other 40% comes from coursework. In my coursework I got 58% (which is a 2:2). I didn't do very well in the exam so I was just wondering how many marks I will need to get at least 40% overall (the exam was out of 300 marks)
2. I asked a friend and they said i should only need around 60 marks to pass! This seems too low to me!
3. 58% of 40% is 23.2%. So you need another 16.8%. So 16.8 / 60 is 28%.

IOW you need to score 28% in the exam to get a 40% average overall ~ 84 marks out of 300.
4. 58%*0.4 + x%*0.6 = 40%

0.232 + 0.6*x = 0.4

x = 0.28

28% out of 300 is 84 marks. Your mate wasn't too far off.
5. ^ I second that. Different method same answer

(y/300 x 0.6) + (0.58 x 0.4) = 0.4

y = 84
