Do you realize that your math grade would have been much better if you tried to find the right answer whenever you get it wrong? It will help you understand so you will get it in the future.
Math is a cumulative knowledge. Anything you learn today is need to learn tomorrow's topic. Everything you learn today is just a preparation for future topics. If you "learn and forget", you are heading for trouble.
