Fall Semester Highlights
Fall sessions kick off in late September, a bit later than some colleges, which can throw off newbies (don’t be one). The tight window to add or drop courses by early October means you should have your schedule locked in fast or risk messing up your plans.

Spring Semesters and Breaks
Spring begins a bit chilly in January but warms up with a well-timed break right before April. That mid-semester pause isn’t just a breather but a critical recharge moment — use it wisely.
Summer Sessions Bring Flexibility
Summer comes in two compact sessions, allowing students to either catch up, get ahead, or explore new topics. The July session especially packs a punch with condensed coursework.
