Struggling with Numerical Analysis

Greetings

I am currently in my second year of physics and one of my required courses is numerical analysis. Here we'll see how to solve problems, such as linear systems of eqns. , differentiation, integration, ODE's and systems of ODE's numerically using MATLAB.

For the moment I am really struggling since the material is not sticking which means that i cannot proceed to exercising, since i don't understand the theory yet.
Besides that we should not only be able to understand algorithms and work out problems on paper, but a big part of the course is learning how to solve these problems using MATLAB.

I'm way better with just pen and paper than I am at programming, barely passing my python final last year with an 11/20.

I am starting to panick a little since it's something I know is really important in physics and right now it's not looking to good for me.

Can anyone give me some advice on how to proceed? Tips on how to learn this material or how you studied this course are also very welcome. I appreciate any help.

Thanks
