Should I notify colleges?

<p>I'm currently a high school senior, and I changed my schedule for second semester, dropping a math class. I know I'm supposed to tell all the colleges I applied to, but do I have to notify them all? </p>

<p>I applied to 8 colleges, but I only told 4 that I dropped the class, mostly because those 4 are the only ones that I want to go to. The other 4 are just ones I applied to for fun or because my parents made me. </p>

<p>Anyways, I've already been accepted at 3, and I'm just waiting for the one college that I really want to go to, which I already notified. </p>

<p>Does it really matter if I tell the colleges I dropped a class if I don't want to go to that college anyways? It really just seems like a waste of time and money for postage.</p>

<p>You don’t have to mail it to them…you can just call or e-mail like I did, or just withdraw apps if you really don’t want to go to them, :p.</p>
