LPC part-time with a full-time jobWatch
Full-time students at BPP doing the LPC are expected to devote around 40/45 hours per week on their studies. Realistically, I probably studied around 60 hours per week. Part-time students are expected to do around half that (20 hours). If your full-time job isn't too strenuous it should be ok but are likely to have to study on the weekends/evenings as well, which might hurt your social life.
To flip it round, many of my peers in the full-time LPC tried to have part-time jobs during the year. They all either switched to part-time or quit their jobs even though they were part time. You should be able to do it, but I'm not sure how healthy your social life will be! Hope this helps!
