Tech covers many different jobs. Pick a direction first, then look at courses in it.
Try the tasks behind the labels
- Web development: build a small page and explain how its parts interact.
- Data work: clean a small dataset and explain a chart or query.
- UX: describe a user problem and sketch a possible interaction.
- Security: study a defensive scenario using authorised learning material, not a real target.
Choose a direction to investigate
These are suggested trial tasks, not job profiles or course promises. Record what you enjoyed, where you needed help and which prerequisites you should study next. Follow the topic pages for source-backed explanations of the subject.
Build a realistic study record
Keep your exercises, decisions and corrections together. Use course material to address a specific skill gap rather than treating a collection of completion badges as proof of readiness for a role.
Documented platform formats
Codecademy provides an integrated code editor where learners can write and run code in the browser. (Codecademy — official documentation)
The catalog distinguishes individual courses, skill paths and career paths. Examples of its subjects include Python, HTML/CSS, SQL-related data work and computer science. (Codecademy — official documentation)
Codecademy lists projects and preparation for external industry certifications as parts of its learning offering. Preparation should not be confused with receiving the external credential. (Codecademy — official documentation)
DataCamp combines short video tutorials with hands-on coding exercises. Its interactive-learning page describes real-time feedback. (Datacamp Interactive — official documentation)
DataCamp describes browser-based exercises that do not require local software installation for that learning environment. This does not remove the need to practise a local setup outside the platform when a project requires one. (Datacamp Interactive — official documentation)
The learning catalog covers Python, R, SQL, Excel, Tableau and Power BI, alongside data-engineering topics. (Datacamp Interactive — official documentation)
Coursera lists individual courses, Specializations, Professional Certificates and online degree programs. These are distinct types of offering, rather than interchangeable credentials. (Coursera — official documentation)
The platform works with universities and companies; its public catalog includes offerings from Google, IBM and universities. The named issuer should be checked on the individual program. (Coursera — official documentation)
Coursera describes previews, trials and paid access as different routes. A preview or a trial should not be described as unrestricted free access to every course or its certificate. (Coursera — official documentation)
