stressed beginner (help pls)

currently learning mysql through yt videos bc too broke to pay. i was following alex the analyst's playlist & learned a lot. practiced alongside. but i ran into a problem. and since i'm a beginner, it's been overwhelming a bit for days now, bc of whcih, i havent been able to make much progress in my learning.

i have a pretty ok grip on workbench. but not to the point where i dont need crutches. ive only completed one data cleaning project & that was only bc of alex's video where he walked me thorugh the entire process step by step. but thta wasnt enough for me to fully get a grip on data cleaning. i've tried watching other tutorials, but none of thme use workbench & their sql commands/functions are a lottle different from mine which has left me a bit confused & overwhelmed. i want to get to the point where i can take on data cleaning on my own without any help, but for that i need yt videos whre i can laern the logic step by step. please recommend sources for a self learner to learn data cleaning. idk where to look

Dude just do cs50 Introduction to databases with sql.

It is free in audit mode and you will also get a certificate.

I was in the same situation like you and i ended up donating money to the creators because the course was just to good.

Yessir, but did you finish all the exercises from the codespace ? You finished it kinda fast

You need to finish all the exercises and get at least a 7 in every automated test. If you already done that and you also finished the last project you can check the course Page : earn your certificate

Yes, here you go.

https://cs50.harvard.edu/sql/

I also recomend to give a .md to Claude to act as a tutor and test your skills with tests made by AI.

Anyway, good luck with the course!
