tamisue,

Try sitting in the front of the class and maybe even wearing foam ear plugs. The reduced visual and auditory stimulation should help you focus on the subject matter.

Different brands/styles of ear plugs block different amounts of sounds. I find the bugle shaped ones (usually orange) block the least. They might take the edge off the room sounds and echos. It would also be worth explaining to the instructor why you are doing this. Most should be understanding and accommodating.

These tricks work very well for my daughter. She uses them for her military training.

Give it a try and let us know how you are doing.

My best to you.
