I am a Hunan examinee (science), 2 points away from the second line. Can I go to the preparatory class of Hunan University of Technology?
Yes, I think your score is enough. Preparatory classes are only preferential policies to take care of minority candidates, and there is no discrimination, only personal psychological factors. As long as you don't attend ethnic classes, you will be treated like ordinary candidates after one year of preparatory course. As long as you study hard, don't relax and get excellent grades during the preparation period, you can get a good major. Good luck!
