Start by asking the course instructor or coordinator if the class recommends or requires a certain type of camera or system. That should be your first filter.

For a first camera, don’t focus only on body specs. A camera that feels comfortable in your hands and has controls you can learn easily is often more important than chasing the newest features. Try handling a few options in person.

Also, don’t put all your budget into the camera body and ignore lenses. Good lenses matter a lot, and it can be smart to leave room in your budget for additional lenses after you begin the course and better understand what you like to shoot.

Think about the local used market too. Choosing a brand with good second-hand availability can save money and make it easier to build your kit over time.

If your course suggests a DSLR, consider not only entry-level models but also the more advanced enthusiast/prosumer lines, since their controls and handling can be better for learning photography seriously.
