Test One

I looked at the past test one and found that there were two questions about history of computers, I felt worried because I could not get the answer if I meet those historical questions. I may need to review the lecture slides to prepare for it. There were also binary questions which was not covered too much in class. I just hope it would not appear in our test...
Fortunately, we could bring aid sheet, unfortunately, not even one piece of notes in my aid sheet related to my test questions.
 I found the test questions about Dr.Racket was not so hard and there were some similar questions of past test. I was not sure the answer for the first question. I could not think too much about the advantage and disadvantage of the electricity. I just wish I could still get some marks on it.
The answers for the test has been posted, I checked the answers online. there was a question :
(+ 2 5 (* 3 (- 7 4)))
I made a stupid mistake!
(- 7 4) should be 3 and I thought it was -3 so my final answer was -2 instead of 16
I should have checked my answers carefully before I  handed the paper in.
Next time, I should be more well-prepared and careful~
