Walk the path
3 stages
Start Excel in Spanish with a university course you can audit, then move to data and official Microsoft training, without selling the edX certificate as if it were free.
Who it is for: Anyone who needs spreadsheets for work and does not want a paid course on day one.
Walk the path
3 stages
Understand what AI is before training models, and only then move to practice that asks for Python.
Who it is for: Anyone who wants to get oriented in AI. If you do not program yet, do the Python path first; we do not skip that step.
Walk the path
3 stages
Learn JavaScript in Spanish: first contact with Cisco, algorithm practice on freeCodeCamp and a second stretch on NetAcad, without selling a third-party exam as if it were free.
Who it is for: Anyone who can already lay out a bit, or comes from the programming path, and wants the browser language with order.
Walk the path
4 stages
Start inbound in Spanish with HubSpot, then Google Actívate’s official overview, and Google Ads on Skillshop if advertising is your job. The conditions are stated: you need an account and each platform issues its own certificate.
Who it is for: Anyone who wants digital marketing without paying a platform on day one.
Walk the path
3 stages
Go from never having programmed to understanding how software is built and publishing a page with HTML, CSS and a bit of JavaScript.
Who it is for: Anyone who does not know where to start and wants a real foundation, not a weekend tutorial.
Walk the path
3 stages
Learn Python with a first contact in Spanish, a serious foundation and project practice, without selling the Coursera certificate as if it were free.
Who it is for: Beginners who want Python for data, automation or a later move into AI.
Walk the path
3 stages
Start SQL in Spanish, practice with PostgreSQL and, if English works for you, close with Harvard’s course. Without selling a Coursera trial as if it were an audit.
Who it is for: Anyone who needs to query data or understands that back-end work asks for databases, not a first programming language.
Walk the path
Concrete questions, with courses from the catalog. No generic filler.

Both can be a start. Doing them in parallel is the usual way to quit. This is how we choose, without inventing a hybrid.

You can start without code. You cannot skip the limit: to go further you will need Python. We say where that line is.

Audit is not “the course and the diploma are free”. We explain the difference so you do not pick a trial thinking it is free.

If you searched for “Cisco Academy”, NetAcad is not only cables. We publish free Python and JavaScript Essentials with an account. Here is the order and who it is for.

The Microsoft Learn path we had is gone. Official Excel training in Spanish remains: videos and guides on the interface, formulas, formatting and pivot tables. It is free. It is not a university diploma.

View pageHarvard’s introductory course to understand programming, algorithms and how software is built. It is demanding, in English, and still a solid starting point if you want a real foundation. If English is a barrier, there are Spanish options in the same cluster.
Harvard · Beginner · English
View pageThe CS50 version focused on Python. It starts from zero and covers functions, data, libraries and projects. Still in English. If you want a first contact in Spanish, start with Cisco or freeCodeCamp.
