<p>Basically because the longer ones tend to be absurdly expensive.<br>
Especially in math/science but I'm open to all suggestions.</p>
<p>SITE, Student Introduction to Engineering at The University of Alabama is a steal at $700 for the week. It is offered 3 different weeks in July. My son went summer after his sophomore year when he was thinking about Engineering, but not sure. It was a great overview of the different disciplines. Good experience to live in a college dorm, eat the food, etc. University of Virginia also has one for rising seniors that is one week and costs $650. No experience with that one, but the online info looks good.</p>
<p>Try Georgetown’s summer institutes. a bunch of different 1 week courses to choose from. I did Broadcast Journalism last summer and it was great!</p>
<p>Bump for more suggestions.</p>
