Questions before enrolling?
What does lifetime access mean?
Lifetime access means the life of the product, service or company. It applies to the lifetime course purchase, not the monthly subscription. Separately bundled resources may have their own access terms.
How does the monthly subscription work?
The course subscription is $59 per month and renews until canceled. Course access is available while subscribed. This is a subscription, not an installment plan that automatically becomes lifetime ownership. You can cancel future renewals.
Are these live classes or recorded lessons?
The lessons are prerecorded for self-paced online study. Live group support is separate from the recorded lessons; consult the current student schedule for support sessions.
Can I download the videos?
No. Course videos are streamed online and are not available for offline download. You need a suitable internet connection to watch.
Does this course award CEUs?
No CEUs are included with this course. Explore CCO Club if you are looking for continuing education opportunities.
What is the refund policy?
Course payments are nonrefundable because digital training is made available after purchase. Review the course fit, materials and access terms before enrolling. Monthly subscribers may cancel future renewals; contact CCO Support if you need help understanding the terms.
