Hi! This is a great question.
My suggestion for this would be make sure that you have your organization and study habits in place so that you may be able to better keep up with your assignments. College is alot different in high school in terms of assignments so knowing how you study best is number one. Also organization is going to be another area you are going to want to focus on. There is going to be alot more information in a shorter time that youa re going to need to take in so I would suggest making sure all of your notes and materials and area you study in stay organized. Hope this helps
