The teacher likes those with good grades but dislikes those with poor grades.

Most teachers have this mentality and prefer students with good academic performance. However, after a few years, students with good academic performance may not necessarily do well as students with poor academic performance.

Although students with poor grades are not outstanding in their studies, just in this aspect, it does not mean that they are not good in everything, nor does it mean that they will not be able to get ahead in their lives.

Everyone is different and has shining points. You may not be good at studying, but you have your strengths in other aspects. Find your shining points and work hard to dig them out. Believe in yourself, as long as you work hard and persist, there will always be something wonderful about you.
