If you're referring to university technical institute, how about looking at their withdrawal procedure, which may possibly mention about tuition reimbursement (if at all) for students wishing to withdrawal.
You're right to be reconsidering whether to attend the school as it's a for-profit learning institution. Therefore, they're usually more interested in "making a profit" rather than the quality of learning. Their course credits usually do *not* transfer to other schools, even if the for-profit school is regionally accredited.
If you're thinking about automotive technician, for instance, or any other job field, the local community college or "county" public vo-tech school may offer the course. Just an fyi that community colleges may have a "continuing education" or "non-credit" course listing, too.
