It was very remiss of me to fail to mention that Julia took her first public exam in October last year, the results were published towards the end of January. She took CIE O level R.E. and got a B- so well done Julia!
For all of Lydia's IGCSEs we used an exam centre in Bristol which was very expensive in time and money although we had no complaints about the centre itself. We used the same centre for this first exam for Julia.
After a bit of Internet searching I found a school in Torquay which accepts external candidates for Edexcel IGCSEs. Julia and I went to visit the examinations officer and all is now in place for her to sit 3 IGCSEs in May/June this year. So lots of Physics, History and English Language work going on at the moment!
