Support the site. Get something back.
The exam maker, the labs, the games and the notes are free, and they stay free. They are paid for by the teachers who buy things in the store, so the best way to support the site is to buy something you will use in your classroom.
Best way to help
Rainy Day Biology: Molecules & Cells
Print, cut and play: 21 activities in 8 game formats, from dominoes to Double Agents, each with a teacher key.
Unit 1 free
The whole course, on cards
Two decks per unit: one to learn the jargon, one to practise using it the way an AP question will ask.
Credits for the AI marker
One balance for both markers: Mark my IA (5 credits a draft) and checking your own marking on a practice paper (1 credit for up to 20 written marks).
Tell a colleague
The site grows by teachers passing it on. Send the exam maker or the guided labs to your department.
Ask your school
The Rainy Day Biology school licence covers every biology teacher in your school for $45: the kind of thing a department budget is for.

Thank you. Every purchase goes on hosting, the AI marker and the time to write the next pack. If you would simply rather say thanks, you can also buy me a coffee.
