Classes are 2 and a half hours a week and so far all of mine have been during the business day. This is usually once a week, but last semester we had two classes that were twice a week for an hour and fifteen minutes instead. Last semester I had 5 classes and this worked out to class being Mondays- Thursdays (2 classes per day except for one on Wednesdays). This semester we have 4 classes and are in class 3 days per week (If you're really interested in specific class times or something, let me know). Half of our group has started clinic in addition to classes this semester while the other half will start clinic in May. Clinic schedule varies from person to person. This has been my schedule with an undergrad degree in speech, so I'm not exactly sure how it differs if you have an extra semester with pre-requisites. There is a lot of work done outside of class such as studying, clinic observations, group meetings, etc.
Classes are already set up for you when you meet with them in June, telling you exactly which classes you will be taking each semester and which semesters you will have clinic. You take the same classes as the rest of your cohort. So there is not much flexibility, but I have found that having a cohort is a very big plus. They have also split us up once or twice, offering two sections of one class at two different times but this is rare. For the most part you have all your classes with the same people and there is one section of a class offered.
They recommend you do not have a job during school, but I'm sure you've heard that already. People do have part time jobs, but flexible ones (babysitting, subbing, etc.). A lot of people decide they cannot work anymore once classes + clinic start. During this coming summer I think many people will work because we will have clinic but no classes. I hope this helps!
