All blue box and EOC problems within 3 months

Just wanted to know if it was possible, to have all the EOC and the blue box problems done within a three month time frame with a full time job?

Probably, but really who knows? It depends on your availability and how easily the material comes to you. 40 hours a week and 70 hours a week are both considered “full time”. I’d say if you’re putting in 70/week it’s much less likely you’ll get it done in 3 months compared to someone working 40/week (obviously).
