Am I the only one that got so excited when I saw his calculator? I've never seen a pink colored one. Kinda weird for me but I want it. This video was useful to me, covered the chapter beautifully 💕

[@boxduck3731]

Hah my maths teacher has that calculator

[@nihartanna8798]

I am about to enter Year 12, a huge step between GCSE and A-Level and your videos are really helping me to get a head start into A-Level, keep up the good work Sir!

[@brendon5139]

Hi, how are you finding year 12?

This video has A level physics content which wasn't much focused by our teacher in school so I used to stumble on these whenever they came in paper. But this video is a rich package and I direly needed it. Thnx:)

[@rapfarsibaza]

Yeah

[@liambarker6300]

Wow

[@haarisghani1827]

Thank you so much for the video and timestamps, it explained the content incredibly well so far and I'm only 10 minutes in! Starting A level Physics in September, it seem like these videos will prove to be very useful!

[@karanbaishkiyar7112]

This video is saving my life for my first Physics exam in class tomorrow thank you so so much!!

I am from south Africa and this is helping alot for my course in uni

I'm trying to do the same. Did watching these videos help you?

[@Sea-qv4sd]

@@orwxh2154 yeah I guess. It’s also pretty handy to just read through your revision guide I think so you’ve got an idea of everything you do throughout the year

Last minute revision

[@jaiminsheth5232]

Could you do a video covering the required practicals in this years advanced info and the possible types of questions you get asked on them.

[@AltF-dd3zm]

If I may be so bold, I think precision = the number of decimal places your data is measured in rather than the consistency across a data set. Consistency across a data set is called 'reliability' I think

[@delete7316]

Aqallah says that precision is consistency across data unfortunately.

[@rapfarsibaza]

An amazing video Cheers 💯👔

[@humayunrashid8351]

Is this video useful for OCR too

[@PhysicsOnline]

It is useful, but I'm planning an OCR specific one too!

[@zagreamer9529]

At the end of the video can you have 10 seconds where your hands aren't on the mindmap so we can copy it down for revision without watching the entire 30 minute video.

[@carzyscenctist]

Answer this question for me, please, is a head scratcher: 1.0 cubic centimetre (cm^3) of a solution contains 0.010g of salt. What is the mass of salt contained in 1 cubic decimetre (dm^3) of the same solution? Textbook says 10g but I disagree, my answer is 0.1g Which answer is correct and Why???

[@lilgooseboi7354]

10g, there are 10cm in 1 dm, but 10^3 cm^3 in 1dm^3

[@SF-fe6ov]

how would you find the uncertainty from a multimeter measurement if you only took one reading for each measurement

[@suzzeth5577]

We're not in maths we're in the real world😭😭😭

[@nandoboiii5215]

Can you make a full recap for Particle Physics/Quantum? These videos are really good! Thanks Sir

[@zhikunli475]

is this video useful for CIE AS levels students as well?

[@DhrumitMehta]

Im in my AS (no pun intended) and I found it quite useful

I never remember prefixes all mentioned on the calculator

I’ve spent the day planning the next videos like this for the year 13 topics!

[@gabriellac.5818]

Hi there, I find your videos well explained and very informative. Is there a possibility that you could make it possible so that I may be able to download your mind maps for each of your videos? For example, when making a video, you would take a picture of the mind-map and put it on your website so that we can download it. That is if you have any time. Thank you, Sir!

[@gabriellita7236]
