I'm doing GCSEs this year and I did one last year as well.
Do I need the buy the certificates? My friend says her sister didnt buy them a few years ago so didn't recieve them. Do you need to buy them if you are getting them for the first time? (not a replacement) If so, how much are they?
(I have a feeling the school bought them for the GCSE in year 10 as they have them already but are planning on giving them with this years ones. It would not make sense for them to get them and risk people not buying them)
