retakes and modules

wanted to know whats could possubly happen.

basically i did my first year at uni and failed two modules and then my uni changed the modules you have to do on that course and made me retake (i was told id be doing the modules i failed alongside others in second year and the only reason i found out i was retaking is because the year i graduated had changed on my student account, no one had actually told me) i THINK ive failed one module again in my retake year but it says its my second time redoing it (because its one of the new modules)

ive emailed my course leader and admin and student support at my uni about this but im anxious so i wanted to know what could potentially happen

Worst case scenario is you'll be taken off the course. It will depend on your university's policies and procedures as every uni handles his differently. I know that answer isn't very reassuring, but I want you to be clear that this is a possibility.
Does your student union have an advice service?

thank you for letting me know, my student account says i have 100 credits for this retake year from the modules i passed and i looked online and it says i need 90 credits to progress into my second year so would that be and inclination that i would not have to be withdrawn?

they do have an advice service, thank you for idea! i will contact them asap.

That's a good sign that you have all of those credits.
Definitely use your SU advice service, they are very familiar with your uni's regs and will be able to support.
