Energy transfer and ecosystems playlist
Photosynthesis, respiration, energy transfers, nitrogen, carbon and phosphorus cycles
This playlist includes:
The metabolic pathways and processes that make up photosynthesis and respiration, all in a 'poster' that shows where each of the parts of the process happen. The limiting factors of photosynthesis are also covered.
Energy transfer through the ecosystem and how humans increase that.
Nutrient cycles (carbon, nitrogen and phosphorus) also in diagrammatic form to aid the learning though not compromising on the detail required.
Effect of harvesting, fertilisers and eutrophication.
Succession -covers primary, secondary and managed/deflected succession.
Every video finishes with worked exam questions. These are
discussed to teach exam strategies, show how the content is applied and highlight the phrases and terminology that get the marks.

As someone whose A level plans had been deterred quickly, discovering biologycarol has been marvelous. I've learned material quicker than I expected as well as be able to quickly grasp onto concepts and answer questions efficiently.
For someone who learns through visual representation, I can't thank her enough for her courses. They're a godsend.
AK (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...
