i have learnt more in one of your 4 minute videos than i have in four years of biology lessons, thank you so much
Damn how bad are your teachers, I thought channels like these were just an add on, not full teaching!
Completely agree although i get Grade 4/5s in science i feel like i barely know anything.First time reviisng actually.and how they dragged on the topic of B2 for like 2 months but it was worth it when i did the mock on B2 i got a 6 on the paper.But it aint worth anything anymore as i had forgotten it.
that's far too relatable
I love The 1975 yessss
Same
Anyone else doing last minute revision?🤘🏾
wow yes hey
Same ! 😅
Same here for tomorrows paper
LOOOL unooo
yep! Good luck everyone

Sir, i just wanna thank you for all you've done for us. You've helped me raise by biology grade from a 5 to an 8 in a span of a few months. Im super anxious for biology paper 1 today but i know we're all going to do great because of you!! Thank you for everything
Good luck for the GSCEs , I am starting my year 10 mocks, you got any advice?
hello! I would just like to say thank you so much for all your help. I watched all your videos on chemistry and made mind maps on all the information you gave. Just had my chemistry exam and I knew how to answer every question because of the help of your videos . Thank you so so much! You are amazing
my exam is tomorrow and i obviously have to watch freesciencelessons
How did it go? I had my triple biology paper yesterday. I'm glad I was watching this, haha.
anyone else cramming before paper 1 tomorrow?
yeah boi
looool yes
Yes
I'm so unlucky, my school made year 9s start GCSEs ugh. I feel like I'm the only year 9 here.

Only you can save me now

very easy to learn from your videos ,i normally watch your videos first then reading my text book.
thank you so much
As instructed by my teacher in my online homework task, I express my deep appreciation for your content and dulcet Welsh tones.
yeet

Word
mocks coming up in 2 weeks this guy is literally helping me through it i don't remember a single thing from yr 8 and 9 tbh
You're a great man who has changed the world for teenagers
It’s a tradition for me to come back to his videos and see all the yr11s commenting… I’ve been doing that since yr7 and have my GCSEs next year ..
It's people likes this that deserve to Knited Thankyou sir for saving my education
Last-minute revision for Year 10 Bio Exam. Great explaining!
exactly
GCSEs now my bro come rewatch 😂😂
You are a life saver I had no idea how to revise science so I watched your videos and wrote notes on the topics of paper 1 biology
Did it work??
he is so good , i understood everything he said more than my own science teachers .
one of my old science teachers swore against this dude. now i know that she was scared of him taking over her entire career.
In the AQA approved book for cell division it has a practical called ‘Observing cell division’ do i need to learn this?
Doing my mocks, good luck for the year 11s out there, doing my first set of year 10 mocks, I had my biology science today, suprisly easy but our teahxer said we can contribuye Friday , needed to revise cell cycle
I've learned a lot from this video. Thank you so much!
biology exam tomorrow morning, im watching your whole bio playlist. saviour
Biology paper 1 tomorrow good luck everyone and we are all grateful to you, you legend!
This man. This man is literally my hero.
Literally you are the best Thanks so much I learn a lot of your videos 💘💘
Legit binge watching this guy
why go to science lessons when u have this man to teach you it all 🐐
I'm relying on this channel to help me pass my GCSEs
2024 AND THIS GUY STILL AT IT 😃
Thank you for these videos, they are so much more helpful than almost all the textbooks we have. Do we need to know about prophase, metaphase etc if we are doing AQA higher tier?
nope, not in the spec
Hi sir, interesting video. I'm just curious as to how does the cells know when to stop dividing, i know that uncontrolled cell division is cancer but even then, how did they cause the cell to keep dividing uncontrollably?
You're so good at what you do thank you so much!!
You didn’t speak about the stages name of the cell cycle eg cytokinesis etc do we need to know that ?
revising for my mocks rn you are saving my life
Take a shot every time he says chromosomes
We're trying to revise not get drunk lool
Take a shot every time his eyebrows go up
I told my older cousin to do it and he said na I can't anymore causeI'm gonna vomit
At least if we die of alcohol poisoning then we won’t have to do our GCSE’s
gonna go college next year doing animal management and to be honest the only school subject (to me) that was actually intresting is science and theres alot of A level Biology in the course animal management. with that said imma be so happy not revising maths next year but im still gonna watch these types of vids, thanks for making my life easy mate :)
WHO HAS BIOLOGY PAPER 1 TOMORROW??
meeeeeeeeeeeeeeeeeeeee
me toooo
Me
Space Worm me 😂
Space Worm meee😭😭
i have my biology mocks in an hour. this is the only way i’ll pass
Tip: put the speed of the video on 0.75x so you can understand all the information
thats an awful tip as u waste more time; if anything, you should speed it up so you can get more revision done - its still understandable on 1.4x speed
Bro this guy is always in my science lesson on the monitor
thank you so much this has been more helpful than my actual teacher
My first science gcse paper is on Tuesday
Thanks a bunch you are huge help especially if you just had an exam for a different subject and science is the next day you allow me to revise even when my brain is scrambled egg
Thank you so much! Have been binge watching your videos, they're so helpful!
Thanks for the comment. I'm glad that the videos are helping.
thankyou, this helped me understand cell division because we have started genes etc
In the Aqa approved book (i have diffferent accounts to ask questions and this is how i always start it you may know me)It says that the lenght of the cell cycle varies and how it grows do i need to know this for the exams for this topic specifically?
I JUST HAD MY EXAM AND BIG THANKS TO YOU I DID WELL❤🎉
Thanks for the comment. I'm happy to have helped.
DID U DO AQA COMBINED TRILOGY HIGHER?!!
@@5sundus i do aqa and my biology paper 1 is next week
@@5sundus that’s on Tuesday
you already had your exam?
Its that time of year these vids are gonna blast in views😂 2024 gsces
this channel is a live saver!
i forgot about my test today
(im doing triple science and i need to maintain scores with 7 - 9)
This is my class work for lockdown
yo same!
This guy is an absolute unit
AQA Biology GCSE tomorrow squad Where you at?
Yeet
thankk youuu sooo mucchh, i learnt more from u than my science teacher.. hes bad at explaining. thank youu
watching this in x1.25 speed to cram in all the last minute revision.
im watching this x1.5
im watching this x2
Yet again, thank you, Sir!
yooo i luv this guy, cuz i can say i revised cuz i was playing his vid while on discord
we love you bro
The AQA spec says we should know three overall stages of the cell cycle. Would these be 1. dna replication, 2. cell growth, 3. mitosis?
yep
Thanks so much! Very useful.
How many time does he lift his eyebrow like does anyone realise 😂😂😂
lmaooo
@@MintyMinho your profile picture is amazing 🥲
dont we need to know the names of the stages of mitosis e.g. prophase, metaphase etc
not with AQA I think
do we?
who else is binge watching for tomorrow...
beticx3
If you go on the playlists on learn every video for all 6 papers trust me you will get a good grade no matter what ( my target grade was a 3 and I got two 8s just from watching these amazing videos)
Ty
What up to my last minuters
ayy
yoooo
hey man
heyyyyy
Yea
Is AQA similar to Edexcel? Am I missing out key information if I'm doing Edexcel or are they the same for the most part. Thank You for your help!
Nice video mate keep it up !!! 👍
URGENT Please help! In my textbook it says "One set of chromosomes is pulled to each end of the cell." It then proceeds to say in the next step "The nucleus divides.". Shouldn't the nucleus divide first to allow the chromosomes to line up at the centre?
This guy is gonna save my life tomorrow
just saying my guy you are a hero
