Unfortune.

It is the last night before Methods Exam 2.
I was determined to complete one exam paper.
So I did (though left the last question due to time constraints).

Then it was time to correct.
I search for the solutions...
Only to discover that I spent two hours doing the wrong exam paper.
Mathematical Methods Exam 2≠ Mathematical Methods (CAS) Exam 2.
Sad.

I want to shoot myself.

LOL, Sarah.
