Trainee registration
There are two ways in: with the joining code of the company that pays for your training, or on your own, by buying the courses you want.
I have a joining code
It is 8 letters and numbers, for example K7M2PQ4A. It is given to you by whoever manages training at the company.
Register on my own
No company or code needed. You buy courses one by one and the certificate is yours.
