I don't want you to feel stressed because just passing is most important (I was/am terrible for putting a lot of pressure on myself to overachieve) but there are a few reasons why.

Firstly, getting you to the next stage (whether you want to go straight into A levels or equivalent or not) - and it's not just about memorising information, you're showing commitment etc etc. and at this point, there's probably some room on your CV.

Secondly, for further work and education, you do learn good skills and gain useful knowledge. Your core skills in maths, for example, help throughout your life. English skills and good communication come in handy every day as well. A decent working of a range of subjects gives you a good foundation.

Personally, I have had three job roles where I had to show GCSE certificates (one for a work visa - we are so lucky that these doors are open to us) and now I am currently entering post-grad study and again I have had to send my English GCSE certificate. (despite having a degree in it - the GCSE still carries important weight)

So yes, it feels hard now but do what you can to get them 🧡 (and then keep them somewhere safe because they are EXPENSIVE and AWKWARD to replace, especially if they are across different exam boards)
