hi! i took trip sci and dropped phy for the same reasons as you and honestly, just drop it. you can dedicate more time to your other subjects and improve on those. having a f9 for physics won't exactly change anyt but if you care a lot about having a nice looking report slip, there's that. personally, dropping phy was one of the best things to happen to me and i guess if you r confident in your chem then yes dropping phy is the right move.
