I post a similar question before, but

Analysis, Computing, Bioscience and Applied Mathematics all are both name of the subject and areas of study.

So, either be written in capital letter (for the first letter)or not written in capital letter are correct

So, I feel very confused confusing.

Which of the texts below should be written in capital letter?

It's up to you. Very generally speaking, if you are thinking about the subject, use a capital. If you are thinking about the area of study, don't use one.

You have more  important problems, as corrected below.
I gained 60 points in the Analysis Research Project.
I gained 60 points in the Computing Module
I attained Bioscience Class.
I have a Applied Mathematics Exercise Sheet.

I got 60 marks / percent on the Analysis Research Project.
I got 60 marks / percent on/in the Computing Module
I passed Bioscience.
I have an Applied Mathematics exercise sheet.

Best wishes, Clive
