I graded myself an A because I wrote a lot and explained every part of the computer.

I never went off topic and think I deserve this grade.

It explains all parts with at least 3 sentences and they explain how they work and what they do.

I graded myself a B because I think I did a pretty good job on doing the timeline on video games .

It explains how games have changed and does not change topic.

It explains from old games to new games from old consoles to new consoles.

And gives examples of them.
