If it is a good school, the TOEFL score must be at least 100. Some people are still not satisfied with the score of 1 10, but 100 should be necessary.
If you take the SAT, it is normal to get more than 2,000 points, especially SAT2, where there are full marks everywhere, and 2000 should be the bottom line.
But whether you can apply for the full prize depends on your extracurricular activities, the award-winning situation and how your recommendation letter is written. The most important thing is the interview. Different universities have different emphases. Therefore, if you get good grades, you may not be admitted, and if you get poor grades, you will definitely not.
Sometimes, it takes luck to win a full prize, but I wish you success anyway!
