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.

I managed to get an A* in A-Level biology. Worth mentioning that, I was taking International A-Level biology (IAL) independently at home [without] private lessons. With your videos, I was able to understand even the complicated topics thoroughly and I was able to make notes using the simple diagrams that you drew in every video. Lastly,I am really happy that I have paid your subscription because it is worth the money :) Millions of thanks :) HM (International Student Summer ’21)

Your Teacher


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

Can I share or copy these materials?
No. All materials are copyright biologycarol. These are for YOUR personal use only and must not be shared or copied. The charge I make for these videos is the only way I can carry on making and improving them. Please help me keep going. I can assure you this is not making me rich 😬! If inconsistencies in IP address data and other evidence of unusual activity is noticed, I reserve the right to cancel your subscription.
How long do I have access to the course?
For a calendar year from the date of subscription. Even If this runs past the end of the academic year this is still very good value (far cheaper than private tuition!).
What If I don't need to subscribe for a full 12 months?
Sadly, only subscriptions for a full calendar year are possible - I cannot get subscriptions to end at the end of summer🙁. I am confident that the quality of the content makes your subscription good value for money, even if you might stop using them before your subscription runs out.
How do I stop recurring subscriptions? I only need this for a year!
Easily sorted! As soon as you have received the email confirming your purchase, log back into biologycarol and click on your picture in top right of the header. Click on Manage subscriptions > Cancel.
What if I'm unhappy with the course?
If you have any doubts check out my YouTube channel (https://www.youtube.com/c/biologycarol ) where you can see a few examples of my videos. As this is digital service, sorry but I am unable to offer refunds. Although my intention is to offer accurate and complete content, I do not guarantee to cover all details of any syllabus and I cannot guarantee that errors or omissions have not been made.
What if I have a technical problem?
Please check the Troubleshooter Guides using the link in the footer. If that advice fails, let me know.

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...
