history: I'm so close to obtaining my associate's. I only have three more classes to take. I've been at it since 2011 (!), but I just got serious in 2016. I'm finally almost done with my associate's degree! I technically started wayyyy back in 2011_comma_ but I just got serious in 2016. Oh that's great! Congratulations on your upcoming finish!
current: Thank you. :) I only have three classes left to take. I'm so excited. 
next: That's amazing. I wish you the best of luck with the remaining classes!
