Questions about IB IA and Extended Essay guides

Which IB subjects are covered?

Maths (AA and AI), Physics, Chemistry and Biology IAs, plus the Extended Essay for every subject. Each IA has a set of guided topic ideas, with the criteria in plain words.

Is it free?

Yes. The topic guides and the Extended Essay guide are free to read. The IA & EE Coach is the paid part: feedback on your own work, from S$15 per step, and your first RQ Check is free.

Will the Coach write or fix my IA or Extended Essay?

No. It asks questions, points to what is missing and checks your numbers. You make every change yourself, and you get a dated integrity record to show your teacher.

What is the teacher-reviewed Draft Check?

The AI Draft Check plus a personal review by Ejaz Ahmad, an IB-certified teacher at Photon Academy, returned within 3 working days. Buy it before your final submission.
