science revision videos never help me understand the content but i stumbled on this video and it helped me with understanding this topic
@@jomanabob2461 That's great to hear. Good luck with your studies.
Could you please make more A Level Videos? This was such a thourough walkthrough and a walkthrough that catered to me who was struggling as Y12 (still Y12). I know that it must be quite demanding to make a video like this but even if you were to release sections of it at a time it would be amazing.
@@LightSpeedMedic-f3g in glad you like them, but this is unlikely to happen for while as I don't teach A-level at the minute, although it is my long-term plan.
W channel saved my yr 11 mocks so far
@@chickennuggetnice_yt5521 Thanks, that's great to hear. I hope you get the results you're looking for.
@@mrjdfield I improved from last time thanks
@chickennuggetnice_yt5521 That's great to hear. Keep working hard!
Edxcel
Is this also for triple chem
Yes....all of the Combined Science content also appears in triple chem, but there will be some things missing.
Hi these are brilliant! Please can you do walkthrough video as for Edexcel Gcse Combined Science Higher Chemistry and Biology walkthrough videos for 2020 and 2021 as no one has done these. Thank you
You’re saving me 😭🫶
I GOT FOUNDATION 5-5 JUST FROM FOLLOWING YOUR VIDEOS ALONE. SIR THANK YOU EVER SO MUCH THESE VIDEOS BANG!!
@@mmx2K That is awesome to hear. Very well done and good luck with whatever you do in year 12.

ur the goat saving my science exams
Good luck, you've got this!
Class of 2024 HYD
you've been carrying my entire science gcse - i cannot thank you enough
Comments like this make it worth my whole doing. Good luck with it all!
@@mrjdfieldsame here 😭 thank you so much mate
@@karmarama9567 Good luck!
thank you so much so much help from this should get a 4 now

One day before
Good luck!
You sound like James acaster and Richard osman. Very helpful video
😂 I'm glad you found it helpful. Good luck today!
Isn’t this paper 1
Which bits? The stuff on cells, microscopes, enzymes, diffusion, osmosis and active transport can come up in either paper.
this guy is saving my life
That's great to hear. Good luck with the exams.
@@mrjdfield thank you my bro
any1 here in 2024?
Yeah 😢
Thanks bro Really helped with alot of things I was struggling with

Just believe that you can and you will! Good luck!
you're my day one i love this video and it goes super fast to support my bad attention span good content
I hope it went well, and good luck with the others!
@@mrjdfield i smashed that paper ty

I know this shouldn't be my main revision but the fast pace of it is so helpful for me, I have really bad attention span and struggle to take it in if its super long because I just zone out, so this has really been saving me haha
That's great to hear, good luck for Wednesday!
Helping to save my physics grade! Thank you!
Good luck, you've got this!
here before my exam on wednesday😭
I have same exam today lol, Good luck 😊
i’m cooked
10 hours left😭😭
You've got this guys, good luck!

Hey sir please do Paper 1 combined science edexcel foundation please 🙏
Yes, it is foundation, but it's for paper 2 not paper 1.
i hope i remember all of this by the time the exam starts😭
Good luck! You'll smash it!
i'm cooked
update: i'm not cooked
Sitting my science GCSEs two years early (so year 9) and I have my biology exam TOMORROW, less than 12 hours away. Praying this will help me out because I haven't even learnt half of the material at all in my classes yet. Wish me luck!!!
Good luck!
@@mrjdfield Thank you, really worried but I did well on my mocks, so hopefully the same goes for my actual exams!!
@@Rzz9029 I had mine today. It was pretty good. How did it go?
@@dravogaming1785 It was alright, sorry for replying so late, I DEFINITELY preferred the chemistry one the other day, but it wasn't too bad. Thanks for asking!!
@@Rzz9029 lol same
My exams tomorrow lol. Thanks
Good luck!
This has been saving my science grades since November
That's great to hear. Good luck tomorrow!
gcse tmr gl
Thanks
Anyone doing 2024 GCSES??
yep
Cooked
Half of this guy explanations is wrong
Which ones? Let me know and I can correct it or explain.
The less magnesium amount the faster its dissolution rate, you meant?
Are you talking about the Core Practical Part 1 (varying acid concentration and measuring how long the magnesium took to be consumed?)? If so, the idea is that at a higher acid concentration, the time for metal to be consumed decreases and therefore the rate must have increased. If this wasn't what you meant, can you clarify your question so I can help you better.
I love you mr field ❤️
Erm....good for you!
Please do this for topic 6 aswell
Here are day before my mock
Good luck!
i can bar;ey here him
Class of 2024 here yet?
hi
Yup
Yep
I think your being watched…
