Field notes
The sample problem is a derivative of cos(x³): the tutor flags the missing chain-rule factor and prompts the student to identify the rule. The page says students can work by pen, finger, or mouse, and can disable spoken guidance. Participation is invitation-only, and the current scope is derivatives; students are asked to decide whether a session may be shared for improvement.
