history: 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. 
current: 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. 
next: Well hopefully the 4 days did good and hey guesses are 50-50 right.
