Hi, I'm Sally.
I made GradePod for you.
I've been teaching IB Physics for over 20 years. I'm a Fellow of the Institute of Physics and the author of multiple IB Physics textbooks. And I genuinely believe that any student, with the right system, can get the grade they want.

I didn't set out to build an online platform. I set out to help the students I couldn't reach in the classroom.
I studied Astrophysics at the University of Edinburgh, then moved to London to train as an actuary. A day trip to Brighton with a university friend (also an astrophysicist, also now a physics teacher) changed everything. After a long conversation, she convinced me to retrain as a teacher. I enrolled at King's College London and never looked back.
After my first post at Whitgift School, I joined Fettes College in Edinburgh, one of the UK's leading boarding schools. In my first year there, I was assigned a class of eight sixth form students: low motivation, limited self-discipline, no particular love of physics. I threw everything at them. Evening classes, weekend sessions, thousands of past papers with detailed feedback.
They still mostly failed their mocks. I was devastated. And then I changed my approach completely.
I applied the 80:20 Pareto Principle and built a clear, structured success path focused on the highest-impact actions. I stopped trying to cover everything and started helping students do the right things in the right order.
It worked. Every single one of them improved.
The following year I was promoted to Head of Physics. By the time I left Fettes in 2013, Physics had become one of the largest and highest-performing departments in the school.
Why I built GradePod
But I kept thinking about the students who weren't in my classroom. The ones at schools without great teachers. The ones who couldn't afford a tutor. The ones working alone at midnight, not knowing where to start.
In 2020, I launched GradePod to bring that same proven system to students everywhere. Every tutorial is free on YouTube. No login, no trial, no catch. The exam pack is there for students who want the structured practice that converts understanding into marks.
GradePod now helps over 5,000 IB Physics students every year. I promise it works.
What GradePod is (and isn't)
GradePod is not a big corporate platform backed by investors. It's one teacher who has spent over 20 years figuring out the most effective way to help students ace IB Physics.
I don't think you should spend your teenage years stressed and overwhelmed about exams. I think you should be able to tackle IB Physics with positivity and a sense of growth, picking up skills along the way that you'll carry through life: how to break down a complex problem, work out what matters most, and prepare effectively under pressure.
GradePod will only ever focus on IB Physics. It will never expand into other subjects, and it will never target schools or teachers as its primary audience. It exists for one reason: to help you ace the IB Physics exam, in the most effective and efficient way possible.
The free tutorials
Every one of the 24 topics in the current IB Physics syllabus is covered with two free videos on YouTube: a concept tutorial that explains the topic clearly at the right level, and an exam technique video with screencast walkthroughs of real past paper questions. That's 50+ videos, all free, no strings attached.
The Exam Pack (£39, one-time) is designed to slot alongside them: worksheets for every topic, a full mock exam, an annotated data booklet, and Paper 1B practice papers — all mapped to the current syllabus. And if you want to go further, the Exam Miracle workshop (£69) covers the most effective exam strategies in detail. No subscription. No upsell treadmill.
What students say
"Thank you for supporting me and running alongside me in this IB Physics course. Getting to a 6 from a 3 in term 1 of grade 11 was not easy, and I certainly could not have done it without your guidance and help. Thank you so much for being such an awesome teacher."

"Sally made me go from "I hate Physics" to "it is not that bad once time and effort is put in." Thank you for all the time and work you put into GradePod."

"Sally has not only been super helpful to fill my gaps in the IB physics curriculum but was also an immense confidence booster that allowed me to have consistent sevens."
