Honestly, I learned a ton in this semester, but that also means I have to take many exams, which leads to an endless nightmare of brainless activity called "Memorizing a bunch of stuff even if you already understand them"! Sadly, for particular 1 subject it was even worse, since the professors tried to teach too much things in such limited time, which resulted in lightening-fast lecture speech and getting most of the students into what I called "DKWHYTHT" mode or even fell asleep=>**DKWHYTHT stands for "Don't Know What the Hell You're Talking about Half of the Time".
But at least I did find out that I'm really into robotics since I found that I enjoyed the control theory class this semester.
p.s. I found a great tip to keep myself from being pessimistic under pressure: Try to focus on the thoughts about how happy and relaxed you'll be after going through all the stuff you hate.
