applying to one university but 2 different courses

i want to apply to 2 similar courses pharmacy and pharmacology but at the same uni, is that allowed and will it impact the likelihood of me getting offers?
example of unis that offer both that i would want to potentially apply for 2 different courses
KCL
UCL
University of Reading

Suggest that you email them and ask them - and also ask if this would require a 2nd Personal Statement.
Bath also offers both subjects, and would accept a dual application with no disadvantage.

I've emailed a few unis already hopefully they get back to me soon.Since they are similar could i not just adjust my personal statement slightly?

Pharmacy is a very specific role - direct healthcare/NHS, usually public facing. Pharmacology is essentially research focussed. See - Choosing between Pharmacy and Pharmacology
This means that any PS trying to cover both would end up very muddled, and is not worth the risk of a multiple rejections. Thisis why its best to ask each Uni about a dual applications, and an alternative PS.

i think i may be able to if i mention something like drug discovery briefly in a pharmacy personal statement

Its much safer to ask each Uni before you apply - you could be risking all your choices,

how would all my choices be at risk

i heard you aren’t allowed to apply for multiple courses at the same uni bcs they might just not give you an offer at all 😭 i wanna apply to 2 almost identical courses at a uni (one’s a 3-year degree, the other comes with a foundation year) but got told even that’s a terrible idea

It’s a waste of a choice.
Ring them up today and ask if they automatically consider applicants for a foundation year entry if they don’t have the grades for year 1. Almost every university does this so you would be using 2 choices to do something automatically covered by 1.
