Looking for the best Cisco Packet Tracer learning resources

Hey everyone!

I’ve been learning cybersecurity for a while now, and I’m comfortable with the fundamentals of networking. I’m still learning and improving every day, but I now want to dive deep into Cisco Packet Tracer and learn it properly through hands-on practice.

My goal is to become comfortable with designing, configuring, troubleshooting, and building different types of networks from scratch.

Can anyone recommend:
- The best YouTube playlists or video courses for Cisco Packet Tracer?

- Any beginner-to-advanced practical labs or practice resources?

- Any websites or free courses that helped you learn Packet Tracer effectively?

I’m looking for resources that are practical rather than just theory, so I can actually start building networks and gain real experience.

Thanks in advance!
I really appreciate any suggestions.
