Honestly a CS Degree will prob not be an excuse to jump to intermediate, a reason I rage at Job listings requesting CS Masters students, where a programming diploma will suffice. I would personally start on Web before Mobile, because mobile is os dependant often.
If you still attend school, try getting linked in Learning using your school email. Free for all students, you may still have the benefit.
Otherwise take a Udemy course on Intro To Web dev for 15$ finish it in a week, and then Jump into React or Angular. I’ve helped CS students with their projects and studying, and while they’re learning the most complicated parts of Development, the result is just math with code. You’d fully utilize your degree creating the BIOs for motherboards more than you would with creating a website. In my 4 years of development, I’ve never had to used any math harder than a quadratic equation.
I would look onto Udemy, and just see how many people have bought and reviewed the course. Also the ones that say “2023 edition”, if you buy them you buy every update after that. So if they make a 2024 update you’ll automically get upgraded. I bought a python course in 2018, and I checked my account and there was 2023 version there. You also wanna take a look at the length of the course. Honestly they are all gonna be the same, it’s a matter of your own drive to make the most out of it.
