Which practice sets feature provides real-time help and resources for students?

Learning skills is the correct answer because this feature is designed to offer students real-time support and access to resources that enhance their understanding and problem-solving abilities. It often includes hints, step-by-step solutions, and links to relevant learning materials, directly assisting students as they work through practice sets. The math keyboard is incorrect because it is a tool for inputting mathematical expressions, not for providing real-time help or resources. Autograding is incorrect because it is a system feature that automatically evaluates student answers, but it does not provide direct learning support or resources during the problem-solving process.
