I see a number of tutor requests similar to this plea for help. I never answer them, or offer to help. A student may well ask, but why? What's wrong with my asking for last-minute help. I'm desperate. And that's precisely the problem. You are desperate, you've waited until the last minute, you want someone to bail you out. Other tutors may be eager to help, but I won't. If you have landed in this predicament, then there are problems you should have addressed much earlier in the course. I wish you would have asked for help way back then. I might have been able to save your class work, so you would have learned what the instructor taught related to grammar, writing, etc. That would have been a better use of your tutor dollars, and you might have been able to work on your own thereafter. Now, you just want someone to save you. You won't have learned the topic or the skill. I'm sorry for you, but if you fail the class, perhaps you will consider finding a tutor at the beginning of the course.
As for tutors who respond to such requests, I would say they are interested in business, maybe more than helping a student. It's not ethical in my view to bail out a flailing student, who then won't learn the needed skills on his or her own. I would ask them to think of their core mission and responsibility to the educational process, which is more than just an income-generating activity.
I know there are many tutors eager for more students, and many more students eager to pass a class they aren't prepared in. I would hope Wyzant isn't the platform to match tutors and students like that. I urge students to think ahead, and tutors to assess their place in the educational system (not market).
