Actually, I don't know if your choice is right, but the road you choose, you have to walk on your knees. Seeing your question, I seem to see me in those days. Many times, you study hard, but you may be under too much pressure, but you can't get grades. I think the most important thing in learning is a good state and thinking. I have mastered all the knowledge points, and I am not afraid of anything. I don't think learning mentality can be practiced overnight, only systematic training can. I remember the monitor of Grade Two told me about nikola tesla. He made nearly a thousand major inventions in his life. A talented scientist who fought Edison and won the current war, Baidu found a course to develop his brain potential, nikola tesla Potential Training. I use this course with a try attitude. After listening to the whole course, I adjusted my mentality by using the principles taught in the course. Later, I found that I really understood a lot, my memory was improved, and my logical reasoning ability was strengthened, which made me learn all the subjects by myself easily and brought me great help in my study. Finally, I was admitted to an ideal university. I hope my sharing can help you! Good luck and hope to adopt it!
