thank you so much for responding, i didn’t expect that you would, honestly, anyway, actually all the other IGCSE subjects I am taking are from Cambridge Board Examinations, not Edexcel, my only Edexcel subject is Human biology, so I guess you mean I should start solving AS level Edexcel Biology as well? for the new topics. I have already solved all the human biology available past papers, by checking from grade boundaries I used to get A but then slowly I raised it to A star (old grading system) I really am aiming to get a 9. Although I know it requires extra hard work. I will make sure that I will solve some AS level Biology edexcel past papers! that’s like the optimum advice. Thank you !
