SRM University — Worst teaching and correction

I'm a student of BSc.Computer science 1st year I'm having problem with my C language teacher she don't know how to teach C language she don't even know the proper basics in that appropriate subject and before exams she will give some questions which comes in exams and asks to mug up those questions I'm came from CBSE stream I don't know how to mug we only know how to learn and understand the topic and we present that only in exam.But here what happening is she is correcting our exam papers and giving very less marks like border marks if we ask what is this we wrote everything correct only know, she says you have to write what is there in my notes exactly how can it be possible if we study only her notes we can't even know the basics and our future will get sucked so many times we complained to our HOD also but she also neglected our problem we want our C Language teacher to get changed we hope this site is the best one to share our problem and do the concern so please take this problem into consideration and do the needful we are fed up with that teacher and our semister is also ahead and my campus is located in kattankalathur Thank you
