Conditional Offer uni

I dont get how does predicted grades work . Lets suppose if i was applying to a uni which has a entry req of 2a* and 1a and on the site it and it only specifies that you should get a* in maths

so they dont care which sub i get the remaining a* ane a from even if its different from my predicted grades ?

like my predicted is a* in chem and a in phy but honestly, i will not be able to get an a* in chem but can easily do that in physics

so will the offer I receive state exclusively that i should match the predicted grade in subs i am given

Please help me out . i been stressing over this for the last week 😭😭.If any alumns who been through the offer can help me out
