Welcome to the JJMPF. I hope you will enjoy this Forum as you enter into this hobby that we all love so much.
I think you don't need any classes for photography. Its a self-learning process, like childhood.
Well, it's true that each person must learn it for himself. But he is better off not having to do it alone and in a vacuum. Education is expensive, but ignorance can cost even more, especially if we head down the wrong path with gear we don't need, or with equipment we will "outgrow" within a relatively short period of time.
There are many ways to accelerate one's learning about photography. Associating with friends who are already familiar with it can be a great help. Participating in forums like this one can be of great assistance as one grows into the hobby. Ask questions. The JJMPF Membership is eager to help as we grow and learn.
There are also any number of tutorial sights which explain the fundamentals. Your fellow Members here can elaborate on or clarify any questions that should come up as you explore those or any such resources. From time to time we learn that there are workshops for those specializing in different aspects of imagemaking... like weddings, portraiture, landscapes, etc.
And don't forget that manual which came with your camera. A lot of good can come from actually knowing what your camera can do and how to use it to its best advantage.
Once you have a grasp of how to operate your camera, you will come face to face with the greatest challenge of all... learning how to SEE and visualize images which will be interesting to your intended audiences, a cut above mere snapshots. Stuff to move the soul.
Ultimately, the images come from the photographer, not the camera. Study the images of people whose works you like best. Learn about them, about what they do, and learn what they say about what they do and think when creating those images. It's not all intuitive at first. There is much to learn.
Best of luck with the adventure. It's enough to keep one learning and growing for a lifetime.
