[sarajan]

please please please please do the whole of alevel biology eventually .. your whole topic vids are Soo helpful and useful .. I'm in y13 and I would love to bulk watch all your vids together and their great for recap instead of finding a video one by one

[abubakrkhan]

For the mitosis stages an acronym is :

I (interphase) Prefer (Prophase) Milk (Metaphase) And (Anaphase) Tea (Telophase) and cytokensis. This really helped me with GSCE.

[jordanparkinson]

YES! I watched biological molecules before I started Sixth Form and it helped so much! I was sooo nervous to see you didn't have any other chapters. Thankyou so so so much! :)

[imani]

i don't know what i would do without you, you literally pulled me through my gcses

[xenne.]

yay literally started this topic today !!

[ahlamabdullahi]

I use "PMAT" for mitosis: Prophase, Metaphase, Anaphase, Telophase

[alexandrarolfe]

please do all topics if possible, i've struggled to find my stride when it comes to revising, but your videos and writing flashcards off them have really become the best way for me so i'd love if you had the chance to do more. you're really saving my a levels, thank you!

[icecold]

Literally just saw "Whole of AQA A level biology" and got so gassed 😂. Thanks tho!

[sevyeyx]

thank you omg i have a mini assessment tomorrow !!! also i love your hair :D

[shafinabi]

Thank you so much these videos are so helpful! would you be able to make past paper walkthroughs please ?

[randomness]

Hello! I know this is completely irrelevant to the video but I’m in year 12 (2nd week) and I’m studying Economics, psychology and politics. Will I be able to apply for a law degree at a Russel group university even though my subjects are not facilitating?? Thanks!

[dlpus]

Pick My Apples Today thats how i remember it

[hadai_el_nour]

A very beautiful, wonderful, attractive and useful channel, good luck and lasting success 🌹🌸🌹🌸🌹🌸🍃🎁🍃🎁🍃🎁🏆🏆🏆💯💯✔️✔️👍👍👍🙋‍♀️

[davidsykala]

Hi, I've got just one question, you mentioned in the video that viruses are prokaryotic, however when I googled it it said they are not, could you just clear that up?

[raze]

Would I be okay using this if I am doing OCR Biology?

[kericannur]

I watch these videos but I’m ocr not aqa…does that make a difference

[Dude-cfhb]

Wait why is this so long?
Oh no what did i sign up for??

[UKINFLUENCERS..]

I'm in year 12 at the moment and I have a test on unit 2 mid march. I don't understand it much lolll

To whoever is reading this— God loves you so so much, He wants to make everything okay with you❤️He knows your pain, He knows how you feel, He loves you so much and for that reason He sent Jesus (the worlds savior😊) to die so that we could all be made right with God if we asked for forgiveness and to start again through Him (because the thing that separates us from God is sin, which everyone of us has done, BUT God loved the world so much that He sent His Son to take the punishment for us & so that through Him we would be forgiven and have eternal life)💕He loves us so much that if we ask for forgiveness and a new start He will give it to us!His love is unconditional, His love is never ending, and His love is for you! He loves you just as much as anybody else! One of His promises is that He will never leave us, He is always going to stay by our side and in fact He always goes before us to work everything out!💕You matter so so much to Him, You are enough for Him, You are never to far away from Him— He loves you always! And the cool thing is that He wants a relationship with you! He wants a relationship with every single person, and He wants to make us all okay again!💕
