Help working out my course grades/ what I need to pass my modules?

I'm confused by all the weightings and grades I have, could anyone help me ?

Modules and 'Credits' (?)

Texts in Time - 30

Reading Genre - 15

Critical Approaches - 15


Assessments and my marks in these modules:

Texts in Time:

Portfolio ( Weighting: 18% , mark: 68%)

Essay (Weighting: 42%, mark: 71%)

Exam (Weighting: 40%, mark: TBA)



Reading Genre:

Presentation (Weighting: 30%, mark: 66%)

Essay (Weighting: 70%, mark: TBA)



Critical Approaches:

Presentation (Weighting: 20%, mark: 73%)

Essay (Weighting: 80%, mark: TBA)



Can anyone work out what I would need in my Texts in Time exam to pass the year? Assuming I have got 70% in my reading genre and critical approaches essays?

Or what I would need in my Texts in Time exam to pass the module?

Anyone brilliant at maths please help!!!

I'll do two examples for you:

Texts in Time:
Portfolio ( Weighting: 18% , mark: 68%)
Essay (Weighting: 42%, mark: 71%)
Exam (Weighting: 40%, mark: TBA)

Assuming 40% is a pass and your coursework doesn't get scaled due to exams
You currently have:
0.18*0.68 + 0.42 * 0.71 = 0.4206
Which is 42% so you have passed.


Critical Approaches:
Presentation (Weighting: 20%, mark: 73%)
Essay (Weighting: 80%, mark: TBA)

You currently have: 0.2*0.73 = 0.146
which is 14.6%
You need 40% to pass so you need to achieve 25.4% of this from your essay.
Now: 0.8*MARK=0.254. Rearranging, we get: MARK = 0.3175 i.e. you need 32% in your essay to pass.
