love this guy
2025🎉
thanks man now i understand
unit 2?
happy birthday ethan lanyon
I found very less videos on national 5 courses this was realy helpful for notes, explanations and recalling. Thanks so much
Thanks for the helpful content! Can you make videos for 3.2 and 3.3 as well?
The videos you make have really helped with my revision for my upcoming prelim! Thank you!
you said today you’d reply to this with “slay, it’s giving sigma”. Will a promise be kept?
Thank you! these videos are so helpful
Thanks for the comment! Glad you like them.
Thank you, your videos have really helped me out with turning around my grades in biology!
Very glad to hear you are finding them useful!
this man is singlehandedly making me pass thank you
thank you so much <3
Do you know which topics I should study for my n5 biology prelims next week, thanks
Which topics should I study for my prelims next week
Hi can you do these for higher human bio
I love u
Real
Carrying me for the prelims right now sir! 🐐🐐
I was wondering when you were going to post the rest of Unit 1 and start Unit 2?
No quiz 😢
So I’ve been told that a nucleus controls ALL cell activities and the cytoplasm is the site of ALL chemical reactions and you won’t get marks ?😢😅
How is ADP + pi = 2 ATP. Shouldnt it be 1 ATP? How is it 2 ATP
It’s 2
Have you got the full AH course up for biology because I can’t find the rest of 1.4 or unit 2, thankyou
Hi! The rest of the unit is now uploaded. Try the Advanced Higher playlist to find any missing videos.
11:08
Do u know when ur gonna upload the rest of unit 1?
there isn’t any more unit 1 ya fud
Finally got there! Apologies.
Hi there sir , could you plss upload higher human since alot of people have realy been asking for it . I only understand the way that you teach therefore im finding that i dont understand afew things and cant get my head around it . I just hope u can . This is on behalf of many ❤ your a great teacher
tbh this is how i learn, just a one-to-one video session.
Sir could you make a video on how to do the math/problem solving questions for higher please 🙏 ❤
saving my prelims one video at a time 🙏
Same 😂
thank you mr mitchell you are a saving grace
Sir do you think youll have the full course done before the final exam this year? Found absolutely 0 online recources for AH apart from ur vids and they help me a lot and im sure they help a lot of other people aswell as there arent any other people doing vids on AH
Yes they should all be done!
Glad your uploading AH, im currently doing higher and find your videos very helpful so next year ill be watching all the AH ones
Glad you’re finding them helpful!
AM SO HAPPY 🎉🎉🎉 Thanks for uploading, my unit 1 test will be a success thanks to you 🫶🏽🙏🏽🫶🏽
Best of luck! Hope they help out.
Hi Mr Mitchell, will you make a video about key area 5? I’ve been surviving off of your videos, since our teacher doesn’t explain the content. Thank you so much for all your videos so far, they’ve been really helpful😄🎉
Will be getting uploaded soon! Hopefully this weekend. Thanks for watching.
This is brilliant thank you they are a great revision resource for our pupils when will You be uploading the remainder of the unit
Thanks very much! Hoping to get some of them up this weekend!
thank you
very helpful!
greAT VIDEO MR MITCHELL WISH YOU A GOOD RECOVERY!
Please we need higher human biology
Please
true king
thank you sir, I only saw this after the test.
Hope it went well!
IM SOOO GLAD YOUR BACK thank you for uploading, prelims will be a success thanks to you ❤🎉🎉🎉🎉
Glad you are enjoying them!
Im glad you're posting more advanced higher biology videos, as it is such a jump from higher
Glad you’re finding them useful. Yes, it’s a lot more content that Higher.
THANK YOU 🎉🎉🎉🎉
hey there’s a question on the 6:28 what u need to know bit and it’s the “basic structure of sperm and egg cells” can u tell me what it is?😭
Hi there. All that is asking is that you know that sperm are smaller than egg cells and possess a tail for movement. Egg cells are circular cells that are larger than sperm and do not possess a tail. Hope that helps!
this video is 4 years ago and the sqa specification was last updated a year ago, do these videos still cover all the content please let me know ur vids are really helpful
Hi, thanks for getting in touch. Yes, all content still matches the course specifications.
@@MrMitchell thank you so much
Thank you! Please keep uploading so we have enough for this years prelim and exam! 🙏
thank you
