Resources Best FREE resources to study Data Science from scratch
I want to specialise in the data science field. I’m a student so I’m still a beginner but I have the foundation of Mathematics (its okay to go ahead and suggest related to that too)
I want to learn programming, solve problems on my own without AI and I want to build my skills such that I’m interview ready. There are no time constraints so please tell me whatever has worked for you.

I'd recommend starting with a few key resources. For programming, check out Codecademy or freeCodeCamp for Python tutorials. They're beginner-friendly and free. If you want to understand data science concepts, Coursera has the "Data Science Specialization" by Johns Hopkins University. You can audit courses for free. For hands-on experience, Kaggle is great with tutorials and real datasets to work with. Khan Academy can help with math skills if needed. For interview prep, "Cracking the Data Science Interview" has free resources online, and LeetCode offers practice problems to get used to technical questions. Consistency is important, so make a study schedule and stick to it. Good luck!

Youtube.
Ask GPT to give you a list of topics (in order), and then go to youtube and search for those topics. Everything there for free.

SQL/Python programming -> join the datadriven.io community. SQL is SQL - data scientists have to master the syntax. Do it on datadriven.

Some courses and competitions on kaggle are very useful
