1, if you have a good foundation and can guarantee at least 6 hours a day (including leisure time), you can consider not quitting your job to take the postgraduate entrance examination. It's hard to say the possibility, it depends on your state!

2. Of course, the more make-up time for math and English, the better, but at least 2 hours each, and more time may be allocated at first.

If the foundation is not good, you'd better sign up for a well-known remedial class. They will help you string together the knowledge points, which can save you a lot of time.

Brother, if you feel good, give more points. Questions also need extra points. I wish you success, hehe!
