Memorizing words is just one of the ways to learn English, but it is not perfect. It should be combined with learning to make sentences. You should be able to use the new words you have learned. Otherwise, when the exam comes, you will feel that you still have nowhere to start, or you can only write sentences without grammar piecemeal. At the same time, you'd better read some English books when you have the chance to improve your English reading ability.

As for the remedy in mathematics, we should re-study the wrong answers in previous tests or exams. If the answer is sloppy, we should ignore it. But if you completely misunderstand the topic or have never studied it at all, you should continue to study again, or ask the examiner if you don't understand it. Be sure to speak thoroughly. We must solve them one by one, and we will certainly make great progress through systematic review and relearning.

I wish you success in your studies. Getting into a good university will make your parents proud of you.
