university with 5s in gcses (?)

i dont know if i can get into uni

i think i can only manage to get merit in my t level science right now
but also my gcse grades are like.. average because they were the predictions from quarantine, so my maths and english are only 5s. i thought it was fine because most people in my secondary got 5s too and were happy for passing but now i feel like i really need more than just passes it's like.. exceeding is the bare minimum everytime i look at a universities entry requirements..
