i just want to say thank you so much! your videos helped me all the way through GCSEs to get grade 9s and you are now helping me through A levels, you truly are the best science teacher ever!
Hi dr Donnelly , I was wondering if you could do a level videos on immunity ? Antigen representation , clonal selection ,clonal expansion , hemoral and cell mediated and things like that anytime soon b4 this session? thanks a lot for everything you do
Hi there. Love your work. I have a question regarding aluminum oxide. What chemicals or oxides except cryolite, can reduce aluminum oxide melting point if you heat them together in a crucible in a furnace? I know this auestion is not in par with the video above but I dont have your email address. I will appreciate your feedback
Hey dr Donnelly quick question would we have to learn more practicals like marble chips exct for rates of reactions and which from ur experience which practical will most likely come out ? Aqa chemistry rates of reaction
You should definitely learn the required practicals that are on the main focus playlists for 2022. Any other practicals that I mention in other videos are worth being aware of (as long as they are not in the "not going to be examined" list).
Hi. I know that lots of students are waiting for that topic. I will be doing it in the very near future. I'm just making my way through the final AS chemistry topic (Equilibria). I have around five more videos to make on that and then I'll be going back to Biology and doing the Immune System.
Hi Sir! My comment on the last video got deleted I think, it was a question asking about GCSEs. Do your playlists for 2022 Combined Science Higher cover EVERYTHING and every topic we need to know? Thank you so much if you can respond, love your content! 😆

Thanks to u sir I knew all the practicals and…. The marble chips one came out ! Thanks again for the help u are a hero in disguise
what's the marble chip one
for AS level cie what do we need to know about insect gas exchange?

@@Freesciencelessons ok so basically I have to check the required practicals from the advanced information right ?
I have made playlists covering the main focus topics in the advanced information, and these include the required practicals.
@@Freesciencelessons ok and thanks again dr!
Hi, do you think the exams will be easier this year, or are the grade boundaries going to be very low anyway?
for the IGCSEs anyway, the grade boundaries for this year are 2019 > x > 2021 (greater than 2021, less than 2019)
hi sir, thanks for your all your help you legend
I've learnt something important
Will you ever do the immune system please
