I’m a high schooler and don’t know much math but I’m interested in metaphysics (currently reading vol 1 of coplestone s history ((new to philosophy)) and logic is important for that. How can I learn it?

Take a course in introductory logic and critical thinking, or, if that is not feasible, work through a textbook (including doing the exercises) that would be used in such a course, such as Baronet's *Logic*, Vaughn's *The Power of Critical Thinking*, etc.

What do you have in mind by logic?

For some open-access logic textbooks that get into formalization (kind of like learning math): https://github.com/OpenLogicProject/OpenLogic/wiki/Other-Logic-Textbooks

You might look at: For All X or the Open Logic Project.

Three other suggestions:

Copi's Introduction to Logic: https://www.amazon.com/Introduction-Logic-Carl-Cohen-Irving/dp/0367376237/ref=sr_1_3?crid=D0Q8GT8VTMRZ&keywords=introduction+to+logic

Kahane, Hausman, and Boardman, Logic and Philosophy: A Modern Introduction: https://www.amazon.com/Logic-Philosophy-Introduction-Howard-Kahane-dp-1624669352/dp/1624669352

Hurley's A Concise Introduction to Logic: https://www.amazon.com/Concise-Introduction-Logic-Patrick-Hurley/dp/1305958098/

There is a youtube series that goes through the text: https://www.youtube.com/playlist?list=PLS8vfA_ckeuZ9UjAHhA1q-ROZGuE_h21V

Or, if you mean something like just "critical thinking" you might try:

Think with Socrates: An Introduction to Critical Thinking, https://global.oup.com/ushe/product/think-with-socrates-9780199331864?cc=us&lang=en
