Resources for educators

Free practice questions and lessons you can embed, link and teach with.

Teachers, bootcamps, bloggers and study groups can use Tech Town questions and lessons for free — on a course site, a blog post, an LMS page or a slide. No sign-up, no fee.

1. Embed a practice question

Every SQL, Python, DSA, Power BI DAX and PySpark practice question has an embeddable card: title, difficulty, company tags, the problem statement and sample tables, with a button that opens the question in the free Tech Town editor. On any question page, open the Question tab and press Embed to copy the code.

The snippet looks like this (replace the area and the question slug):

<iframe src="https://techtown.in/embed/sql/creator-publishing-frequency-twitter/?theme=light"
        width="100%" height="420" style="border:0; max-width:760px;" loading="lazy"
        title="Creator Publishing Frequency — SQL practice question | Tech Town"></iframe>

Areas: sql, py, dsa, dax, spark. The slug is the last part of the question’s URL.
Add ?theme=dark for a dark card that suits dark slides and sites.
Cards are responsive: keep width="100%"; about 420px height fits most questions (the card scrolls inside).

2. Link to lessons your learners need

All lessons are free to read and link to. Popular ones with teachers:

Pandas ↔ SQL cheat sheet — the same query written both ways, side by side.
SQL INNER JOIN, LEFT JOIN and SELF JOIN — with diagrams and runnable examples.
SQL window functions and window frames (ROWS / RANGE).
Question banks: SQL, Python, DSA, Power BI DAX, PySpark, or everything at the Practice Hub.

3. Please credit Tech Town

Embedded cards already carry a “Powered by Tech Town” line. If you quote a question, reuse an example or adapt a lesson in your own material, please add a visible link back to the page you used, for example:

Practice question from <a href="https://techtown.in/practice-problems/">Tech Town</a>

Please don’t republish whole question banks or solutions, and don’t present the material as your own. Need something different — a set of questions for a class, a workshop or a corporate cohort? Contact us.
