As long as you want.  The materials are yours to download and continue to use.  You have access to the course platform and bonus materials for one year.

While you have access to everything immediately, realistically you need one day to review each unit's materials and then take that info to the pool.  You can easily get everything done for the first time in a week.  When you use the materials all season, you'll really get the benefits.

You'll need a computer or tablet, and a phone.  The videos are large and play better on a computer, but you're more likely to take your phone to the pool.  If you don't own a printer, you can have things printed at a copy shop.

Since you have access to all the materials immediately there's no refunds on the course.  Please purchase mindfully.

Yes.  If you don't own a pool, that's ok, but you will need access to a pool.

No.  This is a practice-based course not a certification and does not contain any teaching methodology.  If you want a teaching course, join one of my certification programs.

Absolutely.  All the materials are on the course platform so you can access them anytime.  All the course materials are in English.
