Done with my coaching classes

I have been studying from home since mid November. I didn't appear for any tests or lects that were kept by coaching they were only boards oriented. And I wanted to focus on jee now.Been studying from yt video lects and they're helping me alot .These classes people have organized some nonsense counseling session , which would take around two hours and I really don't want to waste my time on that. They never cared abt us students ,only want to do these useless formalities just so that they can put it on their brochures .They're just insisting to come and attend , and I really don't want to . What excuse should I give them ?
