Depending on specific subjects and the school qualifications you might be able to still go. Some offer re-do classes for maths (mainly in sixth forms) and collages might allow you to retake most while in collage. There are different paths thought, you might want to go into the army which offer 200+ different jobs and if needed, they will literally provide you with GCSE's for whatever you want to be in the army. If i was you i would defiantly look into that, i don't know what you want to be in life but the army most likely have people work those jobs, like vets, engineer, or musicians, lawyer, and more. But if you look into the qualifications of schools to enter and, to do the subjects you want, and their system on redoing GCSE, i'm sure you'll find a school. I'm sure that you'll be fine and good luck on results day! And remember, you can't do anything right now about your GCSE's so just relax and enjoy the summer.
