New Update is Awful

The new update that changed the you level up skills is simply awful. I am no longer able to feel completely comfortable with a subject before it becomes mastered. Recently I was practicing a new concept and I was struggling a lot and didn't get any of the four questions right and the program leveled me up to the practiced level!! I hate this new update. There was nothing wrong with needing to get x correct in a row. It made it certain that I truly understood a topic before I level up in it.
