Overall

I got 62/66 on this multiple choice quiz which was a 94%. I was pretty confident on most of the questions and at least understood what was being asked. I did have to refer to my note and Google to refresh my memory on some topics. I think I should go over my answers a few times and reread the questions slowly. Overall 2018 MCQ

Topics to Review

  1. Comparing loop algorithms:
    • How switching the order of a step inside a loop affects the overall process or the outputs.
    • Robot algorithms to reach the square
  2. How increasing/decreasing bits changes the decimal number of possibilities.
  3. Creating procedures

Questions I got Wrong

Loops

  • The programs both output ten values, but each value displayed by program B is one greater than the corresponding value from program A. A starts from 1 and B starts from 2.

Robot algorithm

  • I need to pay attention to the steps and how you do each step and repeat that process in the same order. I accidentally did it but repeating each step 4 times. I then got confused because in the way I did it the robot would face the outside grid and have nowhere to go.

Increasing bits

  • I just did 128 bits - 32 bits = 96 bits. But I forgot that since it is bits it is base 2, so 2^96

Adjusted Total

  • I forgot to add the final exam score to the maximum of the previous tests. This was an easy mistake.
