According to admissions experts, a student should start the application process at the beginning of their senior year of high school. While universities may set their own deadlines, the majority of applications for normal autumn admission will be due in January. If you know the college you want to attend, applying early is a good idea. That you’ve looked into its programs and, if possible, paid a visit to its campus. However, if you want to compare admission and financial aid offers from several universities, don’t apply early.
