What can i do about my EMT-b cl I was dropped from?

I was three meetings away from being done. I'm 20 years old live in my own place and pay for everything myself. I was 6 hours short from the 140 because of work which i verified. My question is they want me to pay for the cl again but i cannot afford it. And if i have work again I will miss cl it if im going through a hard time. Should i fight this? i had one of the highest grades in the cl. And I applied for mccormicks early in anticipation and got a call back!Thanks
