Online Science Tutor for GCSE students (biology and chemistry focus!)

I am currently studying Pharmacology at King's College London but I am currently taking a break from university and in the meantime tutor year 6 students in English and Maths whilst also going through GCSE Science exam questions with my sister in my free time.
When I teach my sister GCSE biology or chemistry, we watch videos, draw what we learnt and teach each other what we understand and then do exam questions together. My approach is more 'learning' together and identifying the subjects you will need more assistance in and ensuring consistent practice through exam question repetition. I also understand how stressful GCSEs are as I did them not too long ago so I will always be there to listen to concerns or questions outside of tutoring hours as well! In terms of exam boards for GCSE science (I did triple science and got 9 for Biology, 9 for chemistry and 8 for physics and then achieved 2A* for Biology and Chemistry at A-level) I did AQA at GCSE level and OCR for my A-levels.
