school :(

i am literally so upset: i finally skipped a question on a test for the first time. we were supposed to use references from our textbook to back up our responses, but i literally couldn't find anything in any of our readings to back it up. maybe it's because i saved the question for last and managed my time poorly, but it just feels so upsetting that it happened. i still got a good grade on the exam, but i feel bad for disappointing my prof since i did better on my past exam and projects.
