* Your institution's policies: Each college and university sets its own limits on summer course loads. Some might have a maximum number of credit hours, while others might restrict the number of courses you can take concurrently.
* Your academic standing: If you're on academic probation, you might have restrictions on the number of credits you can take.
* Your program requirements: Your major or program might have specific guidelines regarding summer coursework.
* Your own capabilities: Taking a heavy course load during the summer, even if allowed, can be incredibly demanding. It's important to consider your own ability to manage the workload.
To find out how many semester hours *you* can take during the summer, you need to check with your university's registrar's office or your academic advisor. They will have the most up-to-date and accurate information.
