Full-time classes: generally 4.5-5.5 months, and the tuition fee ranges from 16800-26800, but the actual combat of the project is different, some are only a few days, some are half a month, or even more than a month, and the actual combat time of the halo java project seems to be nearly a month; Pegasus training camp seems to be 28 days.
Weekend classes: generally 3 months, the tuition fees vary greatly, depending on how you choose.
If you have a foundation: I suggest going to a weekend class. If you don't have a foundation, I suggest going to a full-time class.
