The Chemistry IGCSE is a great choice if you’re considering a career in the health and clinical professions such as medicine, veterinary science, nursing, dentistry, and forensic science.

Courses Taught by Experts


Health care

For 10+ years, my passion for helping learners develop and grow has driven my career as a teacher. To help me progress even further, I am currently studying to achieve the IQA award. I love reading and I’m a self-professed Harry Potter fan. Talk to me about all things history, rock music, tattoos and true crime podcasts.

Education and Childcare

My 30-year stride in education started with childminding, to working with pupils with Special Educational Needs and Disabilities. I then tutored in a national reading programme and went on to become a Higher-Level TA. I’m elated to say I graduated with a First-Class BA Honours Degree when I was 50 – living proof that it’s never too late to chase your dreams!



Early Years

Beginning my career as an early years practitioner inspired me to step into the world of teaching. I have since elevated my skillset through a range of qualifications including L3 in Assessing Vocational Achievement, L3 in Education & Training and L4 in Internal Quality Assurance. I’m a big kid at heart; I love Disney movies and also dabble in photography.  



STEM and History of Art

Marine biology, jellyfish conservationist, hairdresser, fitness instructor… I have an eclectic backstory! Art is my passion and one of my proudest moments was achieving my Masters in Fine Art. I then requalified as an Art teacher to share my knowledge with my students. For most of my career, I’ve supported vulnerable students with additional needs such as SEMH and SEN.



Counselling and Psychology

I always knew that a career focused around helping people achieve their goals was perfect for me. That’s why I became a tutor. I love to see my student’s confidence flourish as they progress through their courses. It’s important to help them fit their learning goals around their personal commitments so they have the best chance of success!
