text: There are a couple of versions of "trying your best."  If that phrase means trying to study harder, trying to put more time into study, etc., you might be depriving yourself of some needed assistance.  \n\nHave you discussed your difficulties with your teachers?  Most teachers entered the profession because they truly have a desire to help students to learn.  If you take up the issue with a teacher, they or some resources they know might be able to help you with different ways to study which fit your learning style.  Don't try to improve all on your own--ask someone who might be able to help!
