Friends CS 107 is not an easy class. You really need to work hard on this course. Programs done in this course are hard and time consuming so start early, don't wait for the last minute. if you do you will pay for it. If you do all your programs and do all the works like codelabs, qizes and lab assignment, and do fine in exams . You will get a good grade in this class.
***Important advice*** while doing programs do not copy codes from others or give your code to others because you will be penalised for it. Study hard you will succeed.
