But However, to reach their goals, students may have to face and have to prepare themselves to face many (you can also use : a number of, numerous, an erray of, a lot of, just some alternatives) challenges; (the " ; " is usually placed before giving examples or simply enumerations) such as getting enough funds affording the money to pay the fees , preparing an excellent and convincing application, and so on,. But one of the most challenging toughest ones (reread the top of your sentence, you're saying "one of the most challenging challenge", repeating the same idea is called a pleonasm, search for another adjective to decribe how hard it is, like "tough" for instance), is must be to learn the language used in this country's education educational system. And to prove their sufficient language proficiency, they should take a standardised international test with at least a level of B2 a B2 level (upper intermediate).
