If you are determined to go out, I won't talk nonsense with you, just talk about scholarships.
If you have a good bachelor's degree and good ability, you can really apply for many scholarships abroad for further study.
But ~ ~ ~ ~ ~, undergraduate course is not like this. The establishment of undergraduate course is paid education from beginning to end, which is paid by the school to train you. Unlike graduate students who do research with scholarships, the main purpose of undergraduate courses is to pay for their studies.
If you want to go out to study for an undergraduate course, especially if you want to enter a good school, the probability of getting a high scholarship is definitely lower than 1%, and you have to be robbed by a cow.
Some almost schools may give more scholarships to attract attention. Even if there is, and you can get it, is it interesting to go? If you have money at home, you can smash it for fun.
