Should I watch YouTube tutorials or Online Reading Materials when learning Excel?

I'm an IT student from the Philippines, and Excel will be one of the major tools to be used throughout my program for data analyst roles. Just wanna ask if I should watch YouTube tutorials or read online materials like in W3Schools? If both, may I ask for some advice on how to combine and balance these two? I have experience in using Excel recently.

I'm also asking this question when learning how to code. Thank you, and pls don't judge me for asking this. Just wanna tell that I don't have any funds for bootcamps or specialized training if you're wondering.
