Take engineering as an example. Purdue University's major in science and engineering is very powerful, and its name is world-famous. If it is difficult, it must be difficult. Of course, this difficulty does not mean the difficulty in the application process, but the students who apply for Purdue University must have very high language scores, that is to say, if their hardware conditions are hard enough and their strength is strong, then the difficulty is not very high. If their language scores or GPA are not high, it will take some time to study abroad. So, if you want to apply to Purdue University, go ahead. Don't be afraid of other people's problems, just try your best to do what you should do.
