I started the IB [and]decided to try HL Physics as it seemed interesting. It turned out to be very far from my forté and I was consistently getting 3s and 4s in tests and mock exams. So a few months before the exam period of this year, I began to panic...Then I discovered your channel. For four weeks prior to paper one, I virtually worshipped your videos, and worked along to them in my 'Big Book of Revision.' Last week, I received my results. Incredibly and almost unbelievably, I obtained a 6 in HL Physics. Not only that, but I was 3 marks off a 7."
