Don't even bother with the math courses. All throughout the whole app, if you mess up once, they deduct score. Score, to me, displays how well you do. If I am expected to be a perfect math wizard or I'm worthless, then why should I bother? Actual people teach differently, not punish them for every failure. Oh, and if you are even slightly dyslexic? Good luck going through this archaic mess! If you have a perfectionist means of mindset? Here's the bully ready to question your worth in life!
