Pathogens and Immunity (OCR A Level Biology 4.1) 

Thank you so much!!! I'm definitely not revising last minute for a levels!!!

These videos are so much better than whatever we got during lockdown - our teachers just read whatever was on the PowerPoint and the lesson was finished in 30 mins AT MOST.

I was sick for about a week and missed out on school. Turned up to school to find out we had a test on pathogens and immunity the next day and I just wanted to say thank you as i was able to pass the test well.

this has helped me a lot, thanks. i have an exam on this in a few weeks and your videos have been great for revision

58:43 so if the macrophage eats shit, EATS it.......oops.

You’re literally a godsend thank you so much!

Thank you! This has been a great help for me

After this video i have officially watched all of his AS videos in the time period of 2 days😅

ur rlly good do u have full videos like this for a2 content for when I reach year 13?

Hi Sir, I wonder if you have the links to the completed versions of all of these mind maps, that would be great because often at the end of the video your face cam covers the final mind map. I also don’t necessarily have a lot of time before exams to complete the mind maps so if you could share the links that would be so so helpful

Brilliant video as always. Thank you!

Really useful video

Your videos are amazing thank you!!

thanks big man

I cant find the antibiotic video :(

i love it!!
