315 questions are useful, but maybe not enough by themselves.

If you only memorize them, the real exam may feel difficult. Better to also check the official textbook, safety rules, tools, and basic construction words.

For me, 315 questions were enough to pass.

I passed using the 315 questions, but I also reviewed the practical topics on this site.

The exam includes practical questions too, so don’t study only theory.

It can be enough if you use it the right way.

Don’t just memorize answers. Check mistakes, review weak topics, and make sure you understand safety, tools, and work procedures.
