FAQ
Common questions
What do I get with Premium?
Premium gives you unlimited access to every published course lesson and all premium problems with their available solutions while your subscription is active.
Is course access unlimited?
Yes. While Premium is active, you can open every course lesson as often as you need, including premium classes, full notes, and lesson practice paths.
Do I get future Premium content and perks?
Yes. New Premium lessons, problems, eligible solutions, and other included benefits become available automatically while your subscription is active.
Does my subscription renew automatically?
Yes. PayPal renews monthly and yearly subscriptions by default. If you turn auto-renew off, you can reactivate it before access ends and the next regular charge will be scheduled for the end of your current premium period.
Can I transfer or share my Premium access?
Premium is tied to the account used at checkout and intended for one person, so it cannot be transferred to another account or shared with someone else.
Do you have student pricing?
Not at the moment. If you want a shorter commitment, the monthly option is the most flexible way to try Premium.
Can I request a refund?
Refunds are generally not available because Premium access is delivered immediately and the content can be consumed right away. You can use the free lessons and problems before subscribing to decide whether the platform is a good fit. For exceptional billing situations, contact contact@impol.dev and we will review the case at our discretion.
