Huh. Interesting that you can apply for half a year (or two quarters, or whatever, not including the summer) - I can’t imagine it’s common though? It’s certainly set up to be a full year program, not bits and pieces (as opposed to where I’m at now, where I’m sure the expectation is that you’ll be studying continuously, but I had friends who bounced in and out depending on their work schedules that semester and had no problems).
I personally really like the CLD at TaiDa for the 10 hour a week programs & I know you CAN work at a buxiban and do that at the same time - I had friends that did it & it’s not uncommon.
I’d just be very wary of flushing $3K US+ down the toilet if I had a lot of other responsibilities (ie: job) outside of language acquisition. I’ve found that comparisons to regular college course loads aren’t necessarily accurate - I never carried 20 credits a semester, but generally 15 & there is a big big difference between taking five 3 credit classes and then having two (or, in the case of the ICLP, 4) hours of class a day with one subject. I’m used to doing a LOT of independent work, but getting set up in Taipei, learning the city, and then throwing myself into a language on top of everything else I have to do has been exhausting. I think I’d just lay down and die if I had to work 24 hours a week on top of whatever my ICLP schedule will wind up being.
