It's not just money. Generally speaking, it is no problem to have a certain technical foundation and get on well with the examiner in the intermediate level examination. If you only have skills and don't know manners, you may not get a place in every exam. If the basic skills are not so good, it depends on the specific situation. Some examiners will let go, but some examiners will definitely not let go.

The intermediate exam is more advanced than the intermediate exam, and some theoretical knowledge has been involved here. If you only know technology and can't say a "truth", you may not be able to get through this time. Therefore, the intermediate level examination must be supplemented with theoretical knowledge in advance.

Technician my friend took the exam, and that one has research topics and papers. I heard that theoretical knowledge and practical operation should be very NB. Moreover, it seems that it is a combination of several technologies.
