Stuck with SMR, ASIR, networking, systems, or cybersecurity?
You don't need a miracle: you need it explained to you properly.

My name is Rubén Martos. In 2025 I realized something: many students failed not because they were bad, but because nobody explained things to them properly.

I thought, "If I could understand it, I can teach it. And I can do it better."

I am an SMR technician with a distinction for Best Academic Record, Erasmus+ experience, and I am currently in my final year of ASIR (Administrative Systems and Network Administration). I have worked in support, systems, and cybersecurity for companies in Spain and Portugal, and I manage an ethical hacking blog.

Since then, at Avanza de Verdad we have had a clear mission:
that you understand computer science clearly, practically, and with results.

📌 Classes we offer
• SMR, ASIR and IT from scratch
• Networks, Cisco Packet Tracer
• Linux, Windows Server, scripting
• Databases and cybersecurity

🧠 Our method
• Get to the point
• Learning by doing
• Apply what you have learned

🎯 What are you taking with you?
• Clear and direct explanations
• Preparation for resits and exams
• Help with internships, assignments, and projects
• Answering questions even outside of class
• To truly move forward, not just to pass

We're going to make real progress 🚀
