The full-time bootcamp is a 9-week program, from Monday to Friday, 9am - 6pm. To get the most out of the program, you need to be fully committed to it as it is a truly demanding experience (360 hours of code in 9 weeks + the additional time for preparation work). Generally, people who keep a side activity during the bootcamp struggle to keep pace.
The part-time bootcamp is a 24-week program, where students come for two on-campus sessions from 6:30pm to 9:30pm generally on Tuesday evening and Thursday evening and for an additional session on Saturday all day from 10am to 5pm.
In addition, part-time students have some homework and course videos to watch before coming to an on-campus session to benefit the most from the session, e.g. practice, interact with their classmates and ask their questions to teachers instead of listening to a course after a day of work. The part-time program is really a marathon of 24 weeks! It requires students to be rigorous, to do their homework, and be even more committed than for full-time.
Note that the part-time schedule can be slightly adapted in each city and include some breaks for public holidays.
