Today in Khan academy I reviewed some lessons I had done in the past. I refreshed my memory on basic geometry, parallel and perpendicular line, triangle properties and many more. I only had a slight problem on one of the questions I had to do but I found what I had done wrong and corrected it. So on my review I found that I had retained most of my knowledge on the subjects.
I also watched a video on the introduction of magnetism for physics. I learned the basics of magnetism and about the magnetic field and how it affects compasses.
