1, does not make sense to me. I suspect you mean
Oh how I yearn for those days I spent in college when life on the campus was fun.
turned into a more natural form to:
How I yearn for the days when I was a student and campus life was fun.
3. is OK as originally cast.

Yes, to you; agreed.

‘Course’ has a variety of applications; what is meant here is a ‘course of study’ as is being formally used by universities and academics.

You are only speaking for you, yes?

Yes, there is a difference which is why I suspect ‘campus’ is correct when teamed with ‘college’.

The definition of ‘course’ is confirmed by the context so the addition is not needed.
