I am a junior three student, and I want to know what difficult exercise books are in the senior high school entrance examination. Let's introduce math and physics, English. Someone needs to teach the edition. I think it's good to use "key and difficult points" for modular training and "Tian Li 38 sets" for comprehensive training. You can take a look at the difficulty of the senior high school entrance examination and carry out targeted training. The Longmen topic is also very good. If you have the strength and extra ability, you can try Super Classroom, which is a bit difficult. Good luck in the midterm!
