Yes, but only if they are standardized classes/exams. I do not tutor students for their classes unless it’s a Regents or AP class and even then only if it’s to prep them for their final exam.
I only tutor in the context of standardized exams because it allows us to measure progress and prep with a concrete goal in mind. It’s too hard to measure the impact of my tutoring on a student’s classroom performance and so I avoid it. In comparison, standardized exams are more predictable and thus better for me to establish a track record.
I do make exceptions for previous students who I’ve tutored for a standardized exam. They know the deal and what they can expect from the tutoring.
