Logs Summative RETest Analysis

Part 1: Fill out prior to beginning the test.

  1. My score on the practice test was _____/29
  2. I did every question in the provincial exam binder ( Yes or No )
  3. I did all my corrections on the formative quiz ( Yes or No )
  4. I think I should get ____/10 on my homework booklet.

Part 2: Fill out after completing the test.

  1. I think I got _____/26 on the summative test.
  2. I “starred” every question I was unsure on the test. ( Yes or No)
  3. I reread every question to try to find silly mistakes. ( Yes or No)

Part 3: Fill out after you get your test mark back.

1.What was your score out of 26?
2.My test score reflects / does not reflect my understanding.
Comments:
3.Did you make any silly mistakes?
4.What should your mark have been out of 26?_____
5.I plan to rewrite: YES / NO / 6.What was your HW mark out of 10?
7.My HW mark was an accurate predictor (within 10%) / not an accurate predictor of my test score.
Comments:
8.I plan to replace my HW mark: YES / NO
9.I plan to resubmit: YES / NO

10.Circle any that apply to you:

I did my HW every night.I got behind at times but I caught up.I was behind for most of the unit.I didn’t do much HW.

Some parts were confusing but I figured them out. There were some parts that I never figured out. Most of this unit confused me.

I reviewed by notes thoroughly prior to the test. I kind of reviewed my notes prior the test. I did not review my notes.

I made a tough question list and figured them out. I made a list of tough question I did not make a tough question list.

I am t satisfied with my result.I did OK.I am disappointed.

11.Connect the circles above with a line.

12.What will you do to prepare for the next test?
