Precalculus Tutor

Hi,
I'm looking for an online tutor for my son, a high school junior in Texas. He's taking AP Precalculus and AP Physics 1 this year.

What I need most is homework support: someone to work through his daily homework with him, three-four afternoons or evenings a week, about an hour each session. I'm not looking for someone to do the problems for him. I want my son to do the problems but have help where he needs it. If he doesn’t need help, I would like you to let him work, but stay online with him the entire session. I want someone to guide him step by step if he gets stuck, check his understanding, and keep him focused and on track. He has ADHD, so patience and structure matter a lot. This position is two part: 1)high level math support; 2) homework accountability/babysitting.

Preferred schedule: Monday, Tuesday, Thursday: sometime between 4:00–10:00 p.m. US Central Standard Time.

Could you tell me:
1. Your experience with AP Precalculus and AP Physics, or the equivalent topics
2. Whether you've tutored U.S. high school students before
3. Your availability at those times and your hourly rate for three sessions a week
4. Whether you'd do a trial session using one of his actual homework assignments
5. Whether you have reliable internet and use Zoom Whiteboard or other technology to facilitate teaching math and science concepts.

Thank you,
Monika Mitby
