China University of Science and Technology has talents all over the world, so don't worry about being at the bottom, because they are not good enough, and no one will pay attention.
Try to do well in your present study first, and then decide your future life according to the situation when you come to HKUST. To tell the truth, what you think now may not be followed in the future. There are many people who don't do scientific research in HKUST, and there are many ways to choose from. As long as you have your own ideals, it is no problem to work hard along the direction.
