"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."

Hi Chris! Will you be uploading the entire option for Astrophysics? I'm currently revising for my exams and this has been SOOO useful for me. If not, I definitely understand!
@donerphysics
@donerphysics 3 года назад
I believe that the plans for the new syllabus are to have no options. Astronomy will be smaller and in the core. I plan to do those topics that are part of the core.

Is this for Option C: Astrophysics? I'm yet to start this at school and hopefully it is because all of your videos make physics much easier to understand!

This is part of section D.2 for astrophysics. Glad the videos are helping.

Are you now making videos on all the options? Because I would really, really appreciate that so much in these homeschooling times due to Covid 19. Your videos are very helpful. I would follow your religion if you made one
@donerphysics

I have done engineering physics and relativity at the SL level and will continue with more of the astrophysics option. No religion but I plan to do some videos touching on philosophy and the mysterious nature of our universe.

Is the astrophysics syllabus complete on this channel. I would be thrilled if there are only 2 videos which cover the entire syllabus but want to know if there is anything extra I may have to study on my own. Thank you though your videos are really helpful!

I have never taught astrophysics for the present syllabus, and the two videos that I made, were made because they fit into the plans for the upcoming syllabus. As the syllabus is in its final year, I will not be making more astrophysics videos. There is a lot of missing information on cosmology.
