Stuck with SMR, ASIR, networking, systems, or cybersecurity? You don't need a miracle: you need it explained to you properly. I'm Rubén. In 2025 I realized something important: students weren't failing because they weren't good enough, but because nobody was explaining computer science to them in a clear, practical, and direct way, and they were becoming demotivated. And I thought, "If I could understand it, I can teach it. And I can do it better." Today I am a Systems and Networks Technician with a distinction for Best Academic Record, Erasmus+ experience, and I am currently in my final year of ASIR (Administrative Systems and Networks Management). I have worked in support, systems, and cybersecurity for companies in Spain and Portugal, and I manage an ethical hacking blog. Since then, the goal at Avanza de Verdad has been simple: Don't memorize: understand. Don't pass: excel. 📌 Classes we offer • Networks, subnetting, Cisco Packet Tracer • Linux, Windows Server, Active Directory, scripting, virtualization • Cybersecurity, privacy, ethical hacking • Office automation, databases, SQL • Mentoring of SMR and ASIR projects • Digital training for adults 🧠 Real Advancement Method • Understanding is power: You're not here to pass; you're here to understand.
