One key to successful college applications is being organzed about tasks and deadlines. When there is a lot to do, you can pro-actively manage your stress by knowing what needs to be done and when. Choose or create a task checklist that works with your way of thinking and contains all the essential tasks. Start with a general checklist such as the examples linked below. Additionally, each college will have a list of items you need to complete for your application to be considered. Be sure to check each college's Admissions Office website for details.
