Common questions
- Why credits instead of unlimited?
- Because this product costs real money per generation. 100 credits on Pro covers about 6-8 weeks of heavy exam-season use for most students.
- Can I switch plans?
- Yes. Cancel anytime from your dashboard; your credits stay available until end of period.
- What happens if a program doesn't work on my calculator?
- Every generation runs through a software test before download. If you hit an issue on real hardware, we'll refund the credit.
