I regret my a level choices so much

I went into A levels not really knowing what I wanted to do so I picked chem, bio, eng lit and history, because I thought it would keep my doors open for whatever I decide to do. I dropped history after 2 months because I really wasn’t enjoying it.

Anywho, throughout the year more and more I realised I love politics and international relations. It’s what gets me excited basically.

And I just honestly which I could go back into the past and have dropped chemistry instead because it’s so hard! Throughout the year I haven’t done terribly and I’ve gotten As and Bs but I just feel begrudged. Like it just feels so pointless all the effort I put into it when I know I won’t even use it

I honestly don’t even know where this is going. I guess I was wondering has anyone been in the same boat? Like they’ve realised the A levels they picked aren’t really relevant to what they want to do?
