    the best feeling is when he says that u are given the equation in the exam

    Good to be back, used these videos when revising for my GCSE's and came out with a 9. Now I'm recapping in preparation for my Physics Admissions Test for Oxford Uni and its all thanks to the big man ^^^
  • Shaun Donnelly, this is perhaps the very last educational video of yours that I will ever watch, and I have to give you my utmost thanks. I cannot stress enough just how much you've saved my science GCSES. I'll admit that throughout the year I haven't been as diligent in my revision as I should have been, and your videos have been the perfect quick revision tools I've needed. Your hard work and talent for video making and concise yet simple explanations of hard concepts have been just what I've needed to get through subjects I don't like such as physics and in particular chemistry. I've even managed to excel in biology thanks to your videos, something I'd never have seen coming. On behalf of the tens of thousands of students who's grades have been raised due to you, thank you. You're a legend.

    Yesterday I did the last GCSE science exam I will ever have to do. I will be taking A level Physics, Maths and Furthermaths, so unfortunately your videos will not be of much use to me anymore and I just wanted to say thank you. It is looking like I will be obtaining 9s in Biology, Chemistry and Physics and there is no chance that I would have been able to perform so strongly in my exams if it wasn't for your expert guidance and videos. Thank you for your effort and for inspiring many young people, myself included.
  • @xanxious
    a playlist a day should work for revision, right?
  • @TheBest-fj4qy
    Can please do A level Physics and Chemistry, please!!!!!!
  • Extremely helpful magnetism playlist. I went through it and it helped me understand the topic way better than I did in class. Thank you
  • @HJ-yj4xj
    You've saved me... Just covered all of this in 2 hours! I'm going to absorb this info by osmosis in my sleep. Jk I'm going to memorise this and everything in 2 days since the exam is on Friday and it's now almost Thursday...
  • well this has been a whirl final gcse tomorrow and could not have done this without you shaun, you have helped me create hundreds of revision cards and hopefully with biology and chemistry you will carry my a levels. I'm going to miss this in a strange way but thank you for the great videos. :)
  • @HJ-yj4xj
    Sir I did the exam today (triple physics only) and it was AMAZING! THANK YOU SO MUCH FOR THE HELP! all my exams have been great because of you and I can't thank you enough
  • Just wanted to say thank you for everything you've done to help me with these exams. The physics is tomorrow and the only way I'll get a good grade is because of you and your videos. They've been a great help with revision and I can't thank you enough. xx
  • @NehaGupta-sp6qm
    I just want to say thank you for your videos. It is the night before my triple physics exam and I am never going to watch your videos again after tomorrow. You have helped me through the last 2 years to get through my exams and have helped me maintain A* throughout. Thanks a lot for everything!
