As an apprentice in a garage, at first, my daily job was odd jobs. In your spare time, you may look at customers coming and going, how salesmen sell products, and how masters repair cars, which basically won't let you do. Unless the master has a good relationship, he may give some advice, but others also have their own jobs.

However, attending a regular school is different. There will be a unique teaching system in the school, where you can learn newer and more comprehensive skills. The teacher is here all day, so you can ask the teacher at any time if you have any questions, which is very convenient.
