I'm sorry to hear that you're feeling frustrated with your English scores. As a college student who just graduated from high school in 2025, I suggest you first identify your areas for improvement. Figure out which parts you need to work on, and I'm sure your teacher would be happy to help if you ask her!

You do not need a so-called master outside your school to help improve your English proficiency. That would be always less efficient and in some cases, if not always, less reliable. You simply ask your English teacher or turn to supplementary
 grammar books.  But before you request any form of help from others, the most important thing to do is help yourself: you know where your problems are by thinking of what rules
 or knowledge you failed to grasp behind your mistakes or points lost on exam papers. Then you ask for help to tackle your problems. Burying yourself in seas of test papers without reflection on mistakes and target solutions in place is a mere waste of time and of no point.
