A little clarity before you begin.
What counts as one coach reply?
One successfully checked reply saved in your conversation. Nudges and rule explanations count too. Internal checks, failed requests and reopening a saved reply do not use extra replies. If your connection drops after a reply is saved, it will be waiting in your conversation.
Do I need a payment card?
No. Sign in with Google to receive 50 free coach replies, once per account. There is no subscription or automatic charge.
Can I stay with a difficult problem?
Yes. Use your available replies on one problem or across maths, physics and programming. There is no fixed reply limit for an individual problem.
What happens after my 50 replies?
Your conversation and notes stay available to revisit. New coach replies pause when your allowance is used up. Paid plans coming soon; this free allowance does not renew each month.
