<p>tinytrojan, you’ll be fine. The internationals for example have the very last orientation right before classes start and they will be fine too. My D knows of three last year who had no problem getting into the science classes mentioned above.
Early morning classes are generally the least wanted so you’ll be fine there too.</p>
<p>As for TO, they open up spots every orientation, and since you are accepted you will definitely get your classes. It’s just a matter really at the time of your particular orientation to get into your first choice TO class before spots fill up.
You will take TO Core102 and within that there are several options based on reading material and theme. You will be given that list beforehand with a description of each from which to make your choice. The Core111 Writing will correspond with the Core102 that you take.</p>
