8 years ago your videos were so helpful in my preparation for my Chem SL final exam. I randomly just got a video of yours recommended on home page and felt super nostalgic! Keep up the good work!

I did ib like 3 years ago and im back watching your videos purely because you and your videos were the highlight of my year 11 and 12. Each and every one is a masterpiece and you Richard are a comforting genius

I’m one of the M22 kids who just completed their IB journey a couple hours ago, ending it off with Chemistry HL.

From the bottom of my heart I’d like to thank you Mr. Thornley, your videos were an incredible help in my revision and preparation journey for Chemistry HL. Thanks to you, I feel content with my exam performance. I wish you all the best.

Cheers!
