I just took the college entrance examination last year, but fortunately I did well in math. The math score in the college entrance examination is very serious. When it comes to mathematics, the most important thing is the foundation. If you say you haven't studied for three years, you really need to put some pressure on yourself in senior three. Teachers usually have three rounds of review. The first round of review in the first half of senior three is the basic review from scratch, the second round is the reinforcement, and the third round is the trap stage. At this stage, if you still don't have a good foundation, you need to step up and consolidate the basic knowledge. At least you have to get a basic score in the college entrance examination. It is very important to read those propaganda concepts and make a summary of the wrong questions. General solutions to general problems must be well-thought-out. Good luck
