Thinking about self learn from it for my upcoming physics bachleor

so at my university I have the opportunity to replace mech 1 with theoretical physics and then proceed to mech 2. I will be responsible for learning a lot of mech 1--I believe the theo. professor said he goes over calculus of variations and the lagrangian... possibly the Hamiltonian) so I'm pretty lost on how to go about this at all, but i'd imagine a good book would be a decent jumping off point, so any suggestions?

TL;DR: I'm skipping Mech. 1 and I'm responsible to self teach most of it, and I need a book to help me do that.

I'm looking for a physics textbook to self-study over the summer holidays. I'm in year 8, but all the physics books I can find at my level are obvious approximations, use little to no math (I'm around 1 or 2 years ahead in math), and don't go into any depth about anything.

Are there any good textbooks that are both rigorous, and appropriate for my age?
