What form of training 1C to choose?

Question

IT education

They are sent to work to study as a 1c programmer. The boss needs me to be able and apply my knowledge in the field of 1C in the future, for example, to be able to make different forms, reports, requests, to be able to start new directories ...
Now my level of knowledge in 1C (8.3) is to change the size of the printed form, which then move, correct, add a user)). The most difficult thing I had to do was to install a 1C server from 0 and so that the team could work through a thick client.
Actually, the question is the form of education and what knowledge can give me:
the choice is between online (morning or evening), offline (on weekends) and self-study in other free time.
What do you think - what will be faster and more efficient, taking into account the main work (php-bitrix)?
When choosing courses, how can I understand that knowledge will be useful to me, and not superficially abstract?

Answer 1

offline (weekends)

This.
Most of the online courses and some of the non-online ones are just superficial, here you can only watch those that, for example, are recommended by 1C nicknames themselves or that are organized by 1C itself, and not the lisping Vasyan.

Answer 2

Start with a free overview course, and you'll see:
