THANK YOU SO MUCH!! just did the paper 1 today and it went a lot better than i was expecting all thanks to your videos and predictions for the content. Your videos have taught me more in the last few weeks than my teachers have over the last two years!! Thank you so so much have told all my friends biology friends about your channel ahahaa
I can't thank you enough for all the preparation you have given us for this exam, your resources have helped me and my friends immensely. I am so grateful to have found you, thank you
thanks for the tips - ocr paper 1 coming next wednesday, hopefully it goes well for everyone. I've been using your mind map videos as one of my ways of revision and they are very helpful. I don't know what to expect of the papers hopefully they aren't too harsh.
Hey sir, your mindmaps have been so helpful and I could not have done that paper 1 without them! I was wondering if you had a mindmap on 6.3.2 populations and sustainability because I can't find that one on your channel. Cheers
Thankyou so much for everything! You've really made a difference and have done more for me than my actual biology teacher for the past 2 years. Thankyou so much I wish I could tell you how much it means to me and to other people that you have helped. Thankyou for getting me to the end of biology and teaching me how to love the subject. Hope you are well Sir
Got paper 1 in about 3 hours, just wanted to say thank you SO SO much for all of your detailed mindmaps, you helped me get through entire topics in such short spaces of time, I wouldn't have finished my revision without you. P.S. thank you a TON for keeping these resources free, I'm sure everyone else would agree in saying that it's very generous of you and you've helped so many more students than you know because of it :)
Hi sir, been watching your Mindmap videos - finished the AS videos . Now I am in the process of completing the AS papers . I’m weak in module 5 and 6 . There’s not long left now and I’m panicking as I haven’t done many ppq’s . What do you sugggest?
Hi, I have a question: Is Paper 3 (24th June) likely to have more Module 5 and 6 content or Year 12 (3+4 content)? I’m thinking the synoptic non advanced info questions would focus on Year 13 harder topics? How would you recommend I structure my revision to meet the demands of paper 3 which might be the most difficult paper? Thank you!
Sir, What would you to say to this suggest question? A hydatidoform mole is a rare complication of pregnancy that can occur after implantation of the fertilised egg in the uterus. It results in excessive production of hCG and damage to the lining of the womb, leading to miscarriage. Suggest how a hydatdiform mole could increase hCG above normal levels
if you have a percentage uncertainty question where they've read eg. a scale twice would you do 2x and 2x again because the reading was repeated twice so overall 4x percentage uncertainty
No - It depends on how many measurements you take with the same equipment. For example, if you're measuring the mass of potato cylinders before and after placing them in a hypotonic solution then calculating an average change in mass e.g. 2g . The uncertainty of the balance will usually be given e.g. +/- 0.005 if its a 2dp scale. So because you take an initial and final reading (two measurements) the uncertainty is 2x greater not 4x. In my example the % uncertainty would be (0.005x2)/2g x 100 = +/- 0.5% - Hopefully this helps :)
U deserve an MBE sir. Ur channel has helped countless people
You are the GOAT of A level BIology, up there with kings like TL maths and MaChemGuy, many thanks
This man has contributed to my final grade more than any teacher of my own! Absolute legend
Your predicted papers were so useful for the actual thing they were pretty similar. Cant put into words how grateful i am, thanks

@M43K for OCR A? I thought the advance info was pretty accurate down to a T
Man lyke murray
Big up my man
U are a king sir there are barely any good A Level Biology resources but you are saving us all here lord and saviour Mr Murray

Hi! Have you got a folder/drive anywhere where all of the completed mind maps/ PowerPoints are by any chance?
Can someone tell me if the OCR GCSE exams used only or most the advanced information?

is this ocr b?

Thank you!! Do you think I can apply this to Aqa alevel biology too?
For sure!
