history: I studied endlessly for my biology final, and while I was taking the test, I was sure about my responses I studied endlessly for my biology final_comma_ and while I was taking the test_comma_ I felt good about my responses That's great!  Such a satisfying feeling!  Did you get a good grade?
current: Yes! I got an A. It was definitely satisfying to see that my hard work paid off.
next: I hope you were really proud of yourself :-)
