a level choices??

currently, i want to do maths, econ and sociology, but my school offers 4. what should i pick as my 4th if i wanna go into finance? also is it true that sociology isn’t respected by unis (russel group specifically) bcs everything i find online is conflicted, and if it is, should i switch it to psych? i was considering doing english lang or philosophy or chem as my 4th 😭 i’m so stuck. my school only offers business studies as an AS atm and i wanna do all 4 alevels. sorry if im rambling
