What our students say

"I like how this course is different from studying GCSEs - it's more specialised. I find the subject really interesting. I am studying environmental issues in more depth in my EPQ. This course has introduced me to new interests which I want to go on to study at university."

Jemima Boam, previously at Bohunt School

"BTEC Environmental Sustainability is a good option alongside two A levels. It helps to take the pressure off during exam period. Furthermore, the grades are the same as A levels, a D* is the equivalent to an A* for example, but I feel the likelihood of me getting a D* in all coursework based work is greater thatn the chance of me getting an A* in exams. Environmental Sustainability also links well with Geography."
