In 1st year I have subject c & c+ .i am not understaning lectures in classroom.at that time I was satying in mehdipatnam.i asked my friends how to clear the subject.they said we also faced same problem in 1st year.they suggested me join orbit coaching instiute it will be near to you.so I attended demo classes in demo the teaching faculty was explaination was good, so I impressed I paid money in next class and got id card after two days another teacher started teaching his explanation was not good and dictating fastly.i complained managment they said ok .but they didn’t changed faculty.i suggest you don’t pay money early in coaching classes attend classes for 3 days and then pay fee.
