Warm up to Computer Science

These resources will help you practice and strengthen your Computer Science and practical programming skills. Multiple links are provided to cover a wider range of backgrounds, experience and needs.

Python is a great first programming language to learn for beginners, and Java is second to none to learn OOP and intermediate to advanced programming concepts. Java is a must for computer science students, and is also the prescribed programming language for the IB Diploma Programme Computer Science course with the Object Oriented Programming (OOP) option.

Good luck!
