Yes, it is because of my poor grades that I went to higher education and cram schools. My grades in English, math and chemistry were poor, and I felt inferior at first. Later, I applied for three courses in higher education, namely, derivative English in Iraq and America, pointer mathematics in Jiange and chemistry in CSI Gao Fen. I didn't expect the teacher to have a particularly good attitude and the teaching guidance was very patient. You can ask questions in the group at any time if you don't understand, and the teacher will answer them in time. Now my grades in these three courses are obvious, which has increased my confidence.
