my GCSEs were years ago now, but I came across your channel again today. thanks to your videos I got three As in triple science, during some health problems that left me barely able to attend school at all. I couldn't do A levels, but you really sparked a love for science and I'm starting a degree in my mid 20s now. thanks so much for all you do for students today too.
Thank you for your comment, which I appreciate. I'm glad that my videos helped you when you needed it. I wish you all the best for your degree.
Feels so good when he says “you’ll find plenty of question on my revision booklet” 😂😂😂
You lot seriously, I did my GCSEs last year and used this mans videos for clarification. I got all 9s in triple science. They are 100% accurate and specification specific. He's amazing trust me. This content that we are getting for FREE is just crazy,
Thank you Sir 😊
I completed my GCSEs 3 years ago and achieved grades 98 from consistently getting 3s and 4s from year9-10 in combined science all thanks to your videos! I done my a levels last year and achieved A*A*A in bio, chem and psych and am now studying medicine at kcl! I wouldn’t have gotten this far without your help as not only did you improve my grade but gave me my passion for the sciences :)
Coming back for nostalgia purposes. God bless you sir :)
Hey Sir,
Your videos are very helpful, i have exceeded from 2,2 in Y9 to a predicted 9,8 from your videos. You really are a beast man. GCSEs in 9 days, lets hope i get 9,9!!!
protect this man at all costs
Hello Mr Shaun,I have been watching your videos since day 1 thanks to you my chem bio and physics marks are good I hope this channel gets its recognition And I hope You get to your dreams, God Bless You
my gcse exams are very soon and i am depending on you to save me sir. Wish me luck.
Good luck. I hope you get the grades that you want.
Thanks so much for these videos. I have mocks soon, i have watched just a few of your videos so far but im already understanding everything a lot better.
ABSOLUTE LEGEND BIG UP SHAWN
Thank you so much for your videos this year. You’ve helped me and kids all across the country learn science and you’ve actually made it interesting and fun! Thank you so much from me and all students you’ve helped over the years
Thank you for all your lessons, I remember meeting you when you came for a talk at my school about 4-5 years ago and I was still doing my GCSEs, I don't think I'd have passed science without these videos (:
im in year 10 getting ready for my mocks, thank you this is a super helpful vid, keep the good work up!
My GCSE’s for science have just finished today and I have done 6 papers overall that were foundation tier and contained double content. You’re such a lifesaver and you have helped me so much when revising and practically learning new content . It feels surreal to leave your channel and move on, but I thank you so much for helping me on the way : )
Hi sir i just wanted to thank you for all your help and support. i was going from 6s to 8s and 9s in chem all from wtching your videos. and again thank you a lot
Mate you are a great help, just did my biology paper 1 today and got my chemistry next week, i will be watching you videos religiously
I'm homeschooled, and I was convinced I was gonna fail my GCSEs when in comesto them,but after finding this Channel,I think when they come I might have a chance
I would like to give you a big sincere thank you shaun, you've allowed me to get the best grades i've gotten so far, i've just completed my GCSEs and wouldn't be anywhere in science if it wasn't for these tutorials, seriously.. thank you.
Thank you for your videos Mr Freesciencelessons, they support my education very much👍🙏
Hi Sir, I would like to say a huge thank you for your videos, I have mocks next week and your videos are my only hope for getting the grades I wish. I attend a grammar school and all of us are very thankful for you.
Hey there sir!
iI just Bought your PastPapers!
Now I am gonna solve it real QUICK!
hi FreescienceLessons I want to say is thank you for everything because you just helped me ready for my physics exam today! have a great day!
Sir it is my last gcse tomorow, i had started in year 11 with very weak grades, averaging 4s and 5s in sciences, and ur videos are what had helped me get into a better position in my academics, in such a short time, and love each science, enough to take 2 of them (physics and chemistry) for alevel. Thank you for the free videos and free education that you give us, and helping us extremely with our future.
Thank you for your services. It was highly appreciated❤
Thank you so much sir for getting me through science, you have honestly helped me so much as my chemistry teacher in school is honestly horrible at teaching.
I've just finished my final gcse, combined chem, hoping for a 9-9. regardless of my grades, thanks so much for helping with my gcses. what a legend you are.
Hi sir, I did my last science exam yesterday and I just want to thank you for all your videos. They have helped me over the last year massively in all 3 sciences and have made me so much more confident going into my exams. This is especially true in Chemistry as during yr 10 I had a very confusing teacher and hardly learnt anything. But your videos explained everything so clearly that now I'm hoping for a high grade. Thank you so much for helping me and so many other students.
Thank you my guy 🙏🙏🙏 I may have failed my exams but thanks to you, I am confident I won science
I JUST WANT TO SALUTE THIS MAN AS ME AND MY SISTERS GCSES ARE OVER BUT HE IS THE ONE WHO CARRIED US THROUGH SO THANK YOU SHAWN❤❤❤❤🎉🎉🎉🎉
Sir I appreciate you so much.
Shawn you have been a legend
Hi Shaun, just wanted to thank you so much for your videos. They've helped me so much with my GCSEs this year and I don't think I would've done half as well if it wasn't for this channel. Also are you planning on doing A Level Physics videos in the future? Since I noticed you've done A Level Biology and Chemistry so far and I was curious as I'm taking A Level Physics next year.
Hello sir, I hope you’re doing great. I was just wondering but the day before our GCSE exam would you recommend that we do pass exam questions or watch your videos to cover content, thank you
Thank you mr free scienece lesson
Sir, I just want to thank you for all of your videos that you upload. I just wanted to ask, do you have a playlist on the Use of Biological Resources? If you don’t, please make a few videos on this topic, if it’s not a pain for you of course. Thank you!
My GCSEs were last year, I took triple science and was predicted at my December mocks all 6s. After a bit of a panic, I decided it was time to knuckle down and revise hard, so I did pretty much every past paper there had been for each AQA science and every time there was a question I didn’t understand I would use your videos to help me grasp the concept. In the end I came out with three 9s, and I really do put it down to these incredible videos literally saving my exams and constantly being there to refresh previous knowledge. Thank you so much and please don’t stop making these videos as they really do have such a huge effect and help so many of us ❤
GCSE exam tommorow. thank you very much Sir
YOU ARE THE BEST
I have a burning question, what of the 3 sciences is your favourite to teach?
My favourite subject to teach is Chemistry because it looks tricky but it's really just a few key concepts. My favourite subject is actually Biology because it's extremely interesting.
last exam yesterday, thank you for it all sir
Hi Sir,
Apologies if you've responded elsewhere concerning this already, but will you ever be making A-level Physics videos?
I'm afraid that I've never taught A level Physics so I don't think I would do a good job.
Hello Doc, will you be going over the digestion of triglycerides topic for fiest year A level biology? Your videos are saving my life🤝
I have a question about circuits. So do we draw circuits using conventional current, but in questions/scenarios involving current, we use the correct current (electric current)?
Hi sir do you make igcse biology videos by any chance
THATS WHY HES THE GOAT THE GOOAT
I'm currently in year 9 and my exams which are in June. These exams will determine whether I'm doing single science, foundation maths etc. I hope these videos help me. Wish me luck!
sir, why are you uploading the same topic multiple times? I have seen the older video on metals and alloys and i dont understand why you have made a new one.
Hi. I'm gradually redoing all of the GCSE videos. This is to improve both the graphics and the sound. The content will not be changing.
@@Freesciencelessonsoh ok. btw thank you for replying.
No problem.
Hi sir, in past paper Qs for science when it asks when the student in a practical repeated the experiment how do I know if the answer is to calculate the mean or to show that the experiment was more repeatable? Thanks
Both of those could be acceptable depending on the question. I would suggest writing both. However, if you are asked to give ONE reason then pick the one that you think is most likely because in that case, if you write both, the examiners will mark the first one.
Hello sir, do you have electromagnetism playlist?
Yes there's a playlist called magnetism.
Hi freesciencelessons. Wil all the videos from Biology Paper 1 to Physics Paper 2 labelled "For Exams 2024 + 2025" be accessible for those sitting the exams in 2025?
Yes. The reason I labelled these videos like that is because the spec has not changed and will not change before 2025.
@@Freesciencelessons Sorry to bother you again sir but is the spec still the same for 2025 exams? So that way I know I can watch your videos
Yes the spec is still the same for 2025.
GOOD LUCK EVERYONE !!!!!!!!!!!!!!!!!!!
I AM WATCHING YOU
Hi sir could you do a video on the Required Practical - Anti Septic Technique. There aren’t many on here that are simple and easy to understand. Thanks
The one I have is this video, which is for the AQA required practical on culturing microorganisms. If you're not following AQA, then your spec might not be the same.

hi sir, why am i not able to see exam questions in your site for each topic??
The exam boards do not permit the use of exam questions in RUclips videos. So I don't use them.
Has the spec for aqa combined science changed since 2017?
No it's still the same.
hi, i'm not sure, but I can't find topic 6c on your topic 6 playlist??
What is the name of the topic?
Hello sir, do you have a space physics playlist?
Yes it's in the Physics 2 section of the channel.
Hi sir. I was wondering if there was any videos of your going over questions like this:
The student repeated the investigation.
The student used solutions that had different concentrations from the first
investigation.
The student found that 15.5 cm3 of 0.500 mol/dm3 dilute sulfuric acid completely
reacted with 25.0 cm3 of potassium hydroxide solution.
The equation for the reaction is:
2KOH + H2SO4 → K2SO4 + 2H2O
Calculate the concentration of the potassium hydroxide solution in mol/dm3 and in
g/dm3
Relative atomic masses (Ar): H = 1 O = 16 K = 39
This was on the 2019 AQA Chemistry Paper 1 Last question
I get really bogged down by this and don't know how to answer. Is there any videos of yours that will help me answer this question?
Hi. Yes you need these two videos:

my g
Thank you for your work! We will see what it brought to on results day
Hi sir,
Do you ever realise how good looking you are in that suit and tie?
I miss your smile.
Chat I got GCSEs
Where is the 2024 gang?
Oil up g.
