6 days until I pass my "reinforced concrete 2" class

[Busty Doll]

it is not that, attending lectures gives you insight on the exams. It should be illegal.

I passed every single class that I fully attended.

So you are what, year 3 out of a 4-5 year college?

Regardless of whether you learned anything in class, the prof might have been inclined to grade you 5 instead of 4 on the basis of your 100% attendance.
