That's true, but it is a hurdle the OP will need to overcome nonetheless.
When I left the class on my last night, I thanked the teacher for such a good course, asked him what to do with my materials that I didn't need anymore,he advised I could just leave them and donate them to the class, and then we said our goodbyes. Their were only me and 2 others in a class that could of held 20. They knew exactly what they were doing! That was his window to tell me that actually I have 8 weeks left!
With it being such a low attended class they would of noticed for sure that I wasn't showing up, its not like I was ignored in a large class of 50, there were only 3 of us.
