just to add another place to find testing sessions and a another perspective, there are events call Ham fests (a swap meet of sorts for amateur radio) often at these ham fest they will offer testing sessions however I don't think they have classes with them. also I am a little different I recommend buying the study books like what the ARRL offer or Gordon west. I prefer the ARRL material, the reason is the books are great for reference for when one wants to build an antenna or such. One can typically find information about ham fest on social media like local ham radio fb groups and such larger ones will be advertised on the ARRL website and QRZ and so on.
