Bilingual CCNA Study Tutor: Networking Fundamentals and Exam Prep in English or Spanish

From 51 C$ /h

I studied the full CCNA curriculum in 45 days: NetAcad classes plus 150+ hours of theory and hands-on labs in Packet Tracer (OSPF, EIGRP, VLANs, STP, HSRP, ACLs, NAT). I score around 90% on full-length practice exams. I haven't taken the official exam yet (I'm preparing for it myself), so I'm not a certified instructor. What I offer is a recent, hands-on understanding of the material and of where learners get stuck, because I started from zero too.

I teach networking from first principles: why a protocol works, not just what to memorize. We cover IP addressing and subnetting, switching, routing, network services and basic security, with exam-style questions and Packet Tracer labs.

Sessions are in English or Spanish, which helps if you understand the concepts better in Spanish but need the English technical vocabulary the exam uses.

What we can do together:
- Understand topics you're stuck on (subnetting, VLANs, routing, STP)
- Practice exam-style questions and labs
- Build the English technical vocabulary for the exam
- Plan your study order and review weak areas

Online sessions via Zoom or Google Meet. Packet Tracer is free from Cisco NetAcad.

Extra information

Please let me know your current networking knowledge level and target exam date. If you have specific weak areas (subnetting, routing protocols, VLANs, etc.), mention them so I can customize our first session.

No special software required - we'll use free tools and simulators.

First lesson: $19 - we'll check your current level and plan your study.

English Tutoring: Critical Thinking, Business Communication & Conversation

41 C$ /h

Hi, I'm Adiel, a bilingual English/Spanish tutor educated in the U.S. I can explain things in either language when you get stuck, which helps if you think in Spanish first.

I passed Wyzant's subject exams in English, grammar, proofreading, reading and vocabulary, and I work daily in English with customers. I'm not a veteran teacher, so what I offer is clear explanations, real material and lessons built around your goals.

What we can work on:
- Everyday and work conversation
- Job interview practice and resume review
- Emails and professional writing
- Reading comprehension with real articles
- Vocabulary in context, including false friends between English and Spanish

How I teach: we use real content (articles, emails, interview questions) and I ask questions that make you reason in English instead of translating word by word. The tone is calm and focused, with no pressure.

First lesson: 12 for 60 minutes. We'll check your current level, set goals, and plan the next lessons together, so you can see whether my style fits you before committing.

-------
The path and the method are in there; take a little bit of each.

Holding a degree in mathematics from EPFL, I offer private lessons in Geneva or online.

I graduated from EPFL with a degree in mathematics, having completed all the Bachelor's level courses in this discipline. I have gained significant experience tutoring students from middle school to university level (mathematics and physics). I have also assisted with teaching at EPFL, particularly in specialized courses such as analytic geometry (advanced mathematics course), analysis (first and second year Bachelor's level), and linear algebra (first year Bachelor's level). My in-depth mastery of the theory in these disciplines provides me with the skills and teaching abilities necessary to effectively support high school and university students, helping them understand the theoretical concepts in their courses and apply them practically in their exercises.

Typical course: a quick review (adapted to needs) of the essential concepts of the course, followed by practical exercises and oral role-playing (going to the board, discussion on the physical meaning, etc.), as in a competitive oral exam.

All my lessons are prepared in advance based on the topics covered in class (the student specifies their needs from one session to the next). I also create a handout containing sample exercises illustrating different methods, fully corrected and explained by me.

My commitment to my students' success is absolute. I only prioritize motivated students who are ready to put in the necessary effort to progress.

My main focus is on in-depth understanding and the quality of work. Depending on the student's request, I can also suggest exercises to do between sessions (not mandatory, depending on available time and homework already assigned by their school).
