Also you will make a lot of friends and due to the liberty that you will get in college there are chances that you start going out more than you did during your school time. This can lead to having less time for studying and following up with college work. This is why a lot of students have a hard time getting good grades and on the top of it maintaining them during college. Here is how you get and maintain good grades during your college time-
Make sure that you attend your classes regularly. This will help you in maintaining a good percentage of your class attendance and regular interaction with professors also gives you a better idea of what your studies and exams are about .
Get acquainted with your syllabus and don't just study recklessly without any direction. More than studying it is important to study efficiently. You can study efficiently only by time management and knowing what you have to study.
Try to keep up with whatever is happening in your classes. For example if your professor is done with a lesson in her class, make sure that you get back home and do it once on your phone. This makes your concept stronger and in the end during exam time you will have an edge over other people who didn't do this.
If needed you can also go for tutoring and extra help. Some colleges and universities offer free tutoring and extra classes to students who need it. Otherwise you can pay for the extra help and study.
