The most common source of user frustration in Brainback is the attempt-gate. If you feel the tutor is being unhelpful, first check: did you write a real attempt?
The second most common source is the hint ladder. Level 1 hints often feel useless — 'this is a related-rates problem, thanks' — but they're doing work. Sit with them before jumping.
The third is the classifier. It sometimes redirects an Efficiency-mode message that felt clearly non-academic. When this happens, hit 'stay in Efficiency' and the message will go through. We use those decisions as training data for the classifier.
