['Dang, i messed up today. I spent the last 4 days cramming for this final, but still ended up having to guess on some of the questions on the test.', 'Well hopefully the 4 days did good and hey guesses are 50-50 right.', "Yeah man! I'm hopeful that I can still pass haha. I'm just really glad that it's over and I can focus on other things now"]
I think you did fine, even if you had to guess you probably made an educated guess, hopefully your subconscious remembered more.
I studied hard to pass my final and the class, but when the time came for me to take the exam, I completely forgot everything and had to guess for most of the test.
