So this is not an exhaustive list, remember, many variations could appear. Any ideas? Here is another one: a variation with springs with parallel and series - remember, in parallel: kt=k1+k2, in series (1/kt=1/k1+1/k2). Good luck everyone tomorrow! You've worked hard, you're ready! : )
Sorry, this one is a lot harder to speculate on, have a look at my all of astrophysics and all of cosmology videos though, all theory and practicals covered there!

For practicals In the textbooks they have specific numbers allocated for different practicals do I need to remember those and use those exact values in my practical endorsements
not at all, in fact, it is unlikely that practical would appear word for word. I recommend not memorising anything, just understanding the principles behind them. Have a look at the mark schemes and papers for your exam board, chances are, the experiments will be different.
In Practical endorsements Would I need to know the measurements of stuff needed for the practical, e.g. if I read in a textbook that I need 0.5mol of sodium solution, would I need to remember that 0.5mols for my practical exam experiment?
For binary stars why can't you use F = mv2/r to explain why the smaller star travels faster in orbit than the larger mass star and have to use Kepler's third law? Thank you!
You can, in fact Kepler's 3rd Law can be derived from that equation. I think it's a coincidence that T is often given in the questions and hence the mark schemes explain it this way.
They will need to be consistent and frankly I don't think they will be that bad. My guess a bit lower for an A* and a bit higher for a pass. You guys have worked hard and will do very well!

Hi sir, have you seen the OCR A paper 1 for this year? the questions are so strength and it was so different to the other OCR A past papers. May you give me some advice for my revision for paper 2 and paper 3 please? Thank you !!
Paper 2 normally involves more standard questions on fields and medical physics, but you never know. Generally the more questions you solve, the deeper the understanding of physics will be. You can do it!
Sorry pal, won't be able to do it tonight, my all of astrophysics video contains the diffraction grating and all the theory as well. Good luck tomorrow!
I like the simplicity of this channel. But my advice would be : ''giving viewers more credit and not always understimating them is a good way to progress on ^^ '' it's already respectfull anyway🌱✨
I think its important to assume the viewer rlly has no idea what they are doing. They could have missed lessons for example and have to have everything broken down for them. Obv its too late for that now but these videos will be used in future years for future candidates.
