Help with % - trying to work out grades

I'm trying to work out how many marks I have in my uni module so far, and how many I need in my exam next week to get 60% overall for the module.

Please would someone check my answer because I'm not convinced I've done it right! I've done nil to very little maths in the past 4 years and while I've been trying to work this out I keep getting confused!

The module is split into coursework (worth 40%) and an exam (worth 60%)

The coursework is split into an essay (worth 75%) and a presentation (worth 25%)

For the essay I received 55% and for the presentation I received 60%.

What % would I need in my exam to get 60% in the module overall?

I worked out that I would need 62.5% in my exam to get 60% overall, is that right?

so if cw is 40% comprised of essay(75%) and presentation(25%) and also 60% on pres. and 55% essay
so 60% of 25% on presentation is 25x0.6= 15% 55% of 75% = 0.55x75 = 41.25%
so 15+41.25 = 56.25, so 56.25% of 40% = 40x0.5625 =22.5
so 60-22.5 = what is required = 37.5% overall, but to find percentage required if exam comprised of 60% total, then 60xA=37.5 ==> A=37.5/60 ==> A = 62.5%

so 62.5% which is right there is the proof.
