ADVANCED COMPUTER CLASSES – Networks,
From 18 £ /h
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. Because when you understand, you stop depending on luck, the teacher, and the exam. Understanding gives you power, and power changes your life.
• Practice makes perfect: The key to learning is practice. We work with real exercises, problems, and exams—the kind of thing that puts you in the top 1%.
• Support that empowers you: We help you inside and outside the classroom and adapt each session to your needs, through dynamic and motivating classes, where asking questions and making mistakes is the right path.
Let's make real progress, not just pass 🚀
