How to learn AI from scratch

You do not need a degree to start with AI. Most people begin by understanding what it can and cannot do, then add Python and a little maths before building small projects.

Good for: Complete beginners, students and career changers. Typical time: 100–150 hours in total, depending on where you start.

The usual order of steps

1
What AI is and is not≈ 10 h
Machine learning, language models and their limits, with no coding yet.
2
Python basics≈ 30 h
Variables, functions, lists and files: enough to read and write simple programs.
3
The maths you really need≈ 20 h
Averages, probability and the idea of a vector, explained in plain terms.
4
Machine learning fundamentals≈ 40 h
Training a model, testing it, and spotting overfitting.
5
A small project≈ 30 h
For example a text classifier or a chatbot that uses an AI service.

Free or paid?

Many good courses for each step are free; paid ones usually add a certificate, feedback from a teacher or a fixed schedule. Check the current price, dates and age limits on the provider’s own site before you pay.
