As far as special students are concerned, as long as you can lay a good foundation and make good use of some spare time, I believe you will do well in the near future. Now many universities also have such specialized courses, you can try to get in touch with them. Only in this way can you find your own shortcomings and know what you can learn from. This is also a good way. Some students can learn the essence well. If they have such talent now, I believe there should still be good results, because you have to understand that learning such vocal music means being able to endure some boring things, and you have to be really interested in such things.
If you are zero-based, you need to work hard. Only in this way can you do one thing well. Everything needs careful consideration. If you don't have such perseverance, you'd better not waste time on it. The key is whether you can do it well, because there are still many temptations in college, and some people fail because they don't persist in the end. At first, I was full of confidence and spent a lot of money to buy a lot of teaching materials, but in the end I didn't learn anything, because there are too many such things, so what kind of things depends on your perseverance.
As long as you have enough perseverance, that's the best. If you can't be self-disciplined, there is really no need to stick to things that have no results.
