Leaving Cert Stick with HL Maths or change to Physics?

Hi, I am repeating my Leaving Cert after more than 10 years to get into vet med. I have been stuck for subjects that don’t require projects as I am not studying in a school. I don’t actually need to do Maths, I satisfied that requirement in my last Leaving Cert but I am doing it as I thought the bonus points would really help however it’s so time consuming and even with grinds I am struggling. I was toying with the idea of switching to Physics before registering for the exams and possibly it might be slightly easier?
I am doing Chemistry and Biology which I enjoy but can anyone advise me whether it’s better to stick out the Maths or just switch to Physics? I just feel like I haven’t gotten very far at this stage, am starting to go through exam questions and it’s like double Dutch to me. I have mathstutor.ie, studyclix and my grinds teacher but just feel that most of my time is being taken up with this subject and maybe I could devote more time to the rest? Many thanks
