Well, as long as you don't transfer to this master's class, you can transfer if you want. You have said so much, three words are the key points and are related.

You will study advanced mathematics again next semester. When you apply to change your major at the end of your freshman year, you only need to apply. As long as you dare to apply, you will be transferred. There used to be more than a dozen people in our class who changed their majors, and some failed in several subjects, all of them changed.
