I've been a TA for 7 years and recently started about teaching. I'm 47 and my qualifications are GCSE Maths, English, Geography and History grade C and above but Science F. Struggling to find out to do GCSE Science as I believe this is need for Primary School. A colleague told me to sign up for the exam and teach myself. I have no idea what to do next. My only other qualification is NVQ3 in Administration. Any help appreciated! Thanks.
