## Introductory Resources
|
|
|
|
### Learning to Code
|
|
|
|
[Sololearn](https://www.sololearn.com/) has courses on C++, Java, and Python. You don't have to complete the full course.
|
|
|
|
- For C++, we recommend you finish Sololearn up to (but not including) "More on Classes."
|
|
|
|
[[info | Pro Tip]]
|
|
| You do not need to learn pointers (for now). Knowledge of structs and classes is useful but not required.
|
|
|
