Whats makes tests difficult for you? Time? the Questions? The amount of work? the material it covers? For me it is time. and sometimes I can do the work and I can write out the steps to solve them... but sometimes the work gets long and takes up too much time. I have trouble finishing tests due to time ._.
I'd say the complexity of some math problems. There are so many steps to them, thus many chances for errors.
.-. When I'm the first done (In science for example) I'm forced to stand in front of class organizing Mr. Gonzalez's papers.
I like helping the teacher. I always finish tests early So I have extra time. me and my friend always say: hour long tests are 55 minutes too long.
