Well, there is no doubt that studying at college is exhausting and even quite frustrating sometimes. To begin with, it is significant to allocate a few days in order to settle in. The thing is that you will have a lot of information to process which is the reason why it is important to have enough time to figure out what to do and where you are supposed to go.
Perhaps, one of the most important things to remember in this respect is that you need to master the skill of planning. Attend all classes and try to take notes. It will help you to remember better. Be organized and try to hand in all your assignments before the deadline.
Do not forget to visit orientation at the beginning as it will help you get a better understanding of the whole system. Meet with your professors as it will be really useful for you in terms of what you are still supposed to do in order to succeed at that class.
