Hop-hop.

I was warned that I would have to simply memorize economics, but that wasn't the case; I understood it quite well. However, I had problems with physics. I couldn't seem to organize everything in my head. Preparatory courses helped a little, but I still had to memorize rows of formulas. I didn't fully understand some of the more complex processes, although, of course, it didn't come to the point of "along this axis, the cosine of phi flows forward as the cosine." But in general, yes, half of the definitions in physics are just memorized formulas. The problem is that there are a lot of formulas and letters; I only remember the three laws of Newton and Ohm's law now.
