Especially in college. It is important to read and learn ALL material, for it will expand your knowledge. Not to mention all classes (even intro classes) DO deal with what you will be learning for your major. That would just make you look bad, and it would be extremely embarrassing, also the person won’t be coming to you for advice again/won’t really trust your judgment. It is important to know all materials because then when you are out doing your job you do NOT want to seem stupid and give someone the wrong advice or not know what you are talking about. It will make u feel good in the future when you are doing your job and you are able to thoroughly explain things to people, and possibly even friends. Yes, friends may turn to you for advice in the area your career is. So it is important now to read and know/learn all materials.
