"I would just like to say a massive thank you to you for uploading your videos. 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."

At 13:30, why would you round 0.246 to 0.3? Shouldn't it be rounded to 0.2 seeing as the number following it is 4 (which warrants rounding downwards)?

Hi I really like your comprehensive videos. It helped me review my higher topics in Physics 'cos I haven't been teaching for like 12 years in higher level. I got stuck teaching Grade 9 & 10 IGCSE. Can you please give me the link on subscribing Tier 2 cos I think whenever I clicked @t I went to different button. And any suggestion for mode of payment I am from the Philippines.

How do we know whether we have to round off the uncertainty to the measured value or the measured value to the uncertainty?
