Brain is integrated into your simulator environment. It points out what can be improved in your solutions.


It's still best to first troubleshoot yourself, because that's what you'll need to do in the real exam. Also treat Brain's suggestions as hints, not facts. Brain is a language model, so there can still be mistakes.
Please note this is only a feature of the simulator and not available in the real exams. The real exams won't provide a detailed score at all.
