Thermoregulation in ectoderms and endoderms; Excretion and the Liver, Excretion and Osmoregulation via the Kidney
Thermoregulation: How ectoderms ('Cold blooded' animals) and endoderms ('warm blooded' animals) maintain their body temperatures.
Blood glucose regulation: All those horrible terms beginning with 'g' demystified and for OCR students, how the beta cells secrete insulin.
Diabetes: Type I and II, their causes and treatments.
Liver: Describing and explaining homeostasis, negative and positive feedback as well as how the liver is involved in detoxifying the blood, specifically how amino acids are deaminated and turned into urea via the ornithine cycle.
Kidney - structure and function. Gross structure and how the nephron works for osmoregulation and excretion of urea. All the A level detail, but kept simple! Role of ADH and negative feedback, kidney disease and its treatment (haemo and peritoneal dialysis and transplants) and urine analysis, including how pregnancy tests work using monoclonal antibodies.

Thank you! I hadn’t got more then a B for my whole 2 years doing Biology so waking up to an A today was just unbelievable and watching your videos helped my so much with my revision. Will be recommending to anyone I know doing A-Level Biology. JM (Summer ‘21 student)
I'm a qualified biology teacher and online tutor who makes videos on A level biology topics which are clear in their explanations, straightforward in their format and mark-earning in their exam question hints.
I LOVE my subject! But I also know that many A level students want to 'know what they need to know' and need help to unlock the marks in the exams, so I have formatted my videos to be straightforward, clear and pacy. They may not be 'beautiful' (I am no techy!) but the content is high quality.

Frequently Asked Questions
Seeing as you've decided to invest this much in my tuition, can I just check it doesn't make sense for you to buy one of my Playlist Bundles instead?
The Year 1 (AS) Playlist Bundle gives you ALL the videos that cover the first year of the course for AQA and OCR A for £50 for a year's subscription (full price). These will cover the main AS content, at least, for every exam board.
The Year 1 & Year 2 Playlist Bundle gives you ALL the videos that cover the content for the whole of the AQA and OCR A courses for £100 for a year's subscription (full price). These will cover the majority of the content for any other exam board.
Both of these bundles are ridiculous value for money 😁, being equivalent to 1 or 2 hours of private tuition...
