FINISHED! (well almost)

I have finally completed all of the exercises on the Khan Academy. I thought I was finished a day ago, but then I noticed a small green dot on my knowledge map. A new exercise had been added. This is a great sign that the work is in progress and there are more topics to come.

As of now my project is still not complete. I still have the larger challenges to complete along with a total review. Originally I intended to complete the challenges, and then go back and tie up loose ends with the review, but my first attempt at the challenges proved to be too difficult. I think I am going to need an organized review that covers the proper exercises, then proceed to the review. Once again, I think this is going to take me some more time.

Then engines have slowed slightly recently. Work and a new side project are draining time from the KA project, but I do still plan to finish. I was hoping that someone might catch wind of my attempts and proceed on their own with the same goal. I am sure someone with more knowledge, say a high school math teacher or a college math major, could knock this off in a week or two.

If you do take up the challenge, please let me know!

One Exercise Left

I only have Kinematic Equations left. I have been busy and a bit distracted. I just picked up a 1200 page book and I took a day last weekend to carve out 100,000 points on

I got to the 9th problem on Kinematic Equations twice. These problems, I think, are a poor use of KA. There are far too many steps that involve rounding and I think doing the problems in different ways can yield slightly different answers. The tool breaks down here.

Regardless, I want to plug on. Tonight I finish Kinematic, then I only have 2 Challenges (could take some time) and an almost full review.

One note about review: I think once you have reviewed a problem set once, or maybe once you have completed the corresponding challenge, that you don't have to review again. My map is very orange, but many of the early exercises remain blue.

Off to work.
