Honestly, foundations is nothing like the rest of your law degree. It's a matter for you whether you don't think the degree is for you, and why you did it in the first place. If you have an early sign that you don't want to do it, it's a long and very hard degree, better to quite now rather than later. Foundations of Law is very theoretical and wishy washy and doesn't even count to your actual law WAM. It's more focused on developing very basic skills such as learning to read cases and statute and contextual understanding of the separation of powers and historical background etc. I would wait until Torts next semester to get a better feel for what a law degree will be like, because they're very different types of learning. The remainder of your law subjects other than ethics and jurisprudence will have basically no theoretical waffle and will just be problem questions basically, which is closer to what practice is actually like.
If you have absolutely no interest or passion in law, drop it. They make you do it as a double because the drop out rate is high. You can drop the law component easily, or otherwise look for a transfer internally or externally.
