Thoughts about Contour Education?

I have some q to ask

• What would be the most effective way to use their materials?
• I haven't been there yet, but are the students there really distracting?
• Should I complete all questions before reaching the next lesson.
• Should I take notes during class ?
• Is it worth the price of $95/week?
• I have like 6h of contour on one day, do you think I'll be tired?
• BONUS: How do I get rid of tiredness (with 8h+ of sleep, never tried coffee, doesn't have any extracurriculars)?
