<p>Years ago, I went to a very large high school (graduating class of around 700). About 10-20% of my graduating class went to the same large, IS, public school that I attended (so around 100 give or take).</p>
<p>Freshman year I occasionally saw a few of my former classmates around the dorms or walking between classes. Sophomore year when many students had moved off campus, I spoke to former classmates a few times on the phone. By junior and senior years, I don’t believe I saw a single person I had attended high school with at any time during the year.</p>
<p>Chances are even if you have the same major as former classmates, you will rarely see them in a class unless you make an attempt to schedule courses together, which is much more difficult in college than in high school.</p>
<p>Some kids go to college intent on becoming roommates with friends from home. For some it works out, but many find that living together is a completely different experience than being friends and choose not to continue on that path.</p>
<p>College has so many more groups and activities than high school, that former friends and classmates will probably each discover their own niche.</p>
<p>At a school with 30,000 people even 100, even 200 kids is such a small percentage that aside from a few chance encounters, you will never see each other unless you make an effort to do so.</p>
<p>So, while it may seem intimidating to go to a shool where you know no one and knowing that there are former classmates around to talk to or spend time with provides a level of comfort, odds are that even if you attend a large school with former classmates that you will each find your own path and ultimately the experience will not be that much different.</p>
<p>(Of course I assume that a smaller school where the same students interact more frequently would provide a different experience).</p>
