Hey! 😊 I’m Ruhi.
When I started looking into data science, I found it easiest to break it down into steps. I first learned some Python basics, then got comfortable with Pandas and Matplotlib to play with datasets. After that, I brushed up on stats (mean, median, probability, correlation) and slowly moved into simple machine learning models like regression and decision trees.

The biggest help was working on small projects from Kaggle — like predicting house prices or analysing tweets — and sharing them on GitHub. It’s a great way to learn while building a portfolio.

If you’re just starting, I’d suggest: start with Python → practice with data → learn some stats → try basic ML → keep building projects.

Honestly, data science is quite tough it was one of the hardest subjects for me back in university. I usually learned most of the concepts from YouTube; there are some really great channels that explain things in a simple, practical way.
