When you’re filling out college applications, it’s important to be as clear as possible. You should also use the space provided to explain anything that might look out of place. Why did you suddenly get four C’s one semester? Why did you switch schools three times? Why were you involved in activities until the end of your sophomore year, but nothing thereafter? If you don’t explain those kinds of anomalies, admissions officers have to guess, as explained in yet another great post on the University of Virginia’s blog.
