Was wondering about the new exams for the 4th class. Has anyone done these yet? Wondering about the math, thermo and electrotech ones in particular, don’t know how in depth the 4th class would go into these subjects.

I would look at this and tailor your study to what the syllabus requires

Have you completed any of these exams yet?
