Free Samacheer Kalvi online tests for Tamil Nadu State Board
TN Online Test offers free, chapter-wise multiple-choice practice built on the Tamil Nadu State Board (Samacheer Kalvi) syllabus. Every test is drawn from the book back questions printed at the end of each textbook chapter, plus additional one-mark questions in the same style, so you practise the part of the paper that is easiest to secure marks on.
Pick a class above to see its subjects, open a subject to see its chapters, then start a chapter test. Each question shows you the correct option and a worked explanation, so you learn the method instead of memorising an answer.
What "book back questions" means
Book back questions are the exercises printed at the end of every Samacheer Kalvi textbook chapter. In the Tamil Nadu public exam the paper opens with a one-mark objective section, and those one-mark questions are drawn heavily from this set. Working through them chapter by chapter is one of the most reliable ways to lift a total, which is why every chapter on this site is organised around them.
Structured just like your textbook
Practice is organised the same way your textbook is, by class, subject and chapter, so you can revise precisely the topic your school is teaching this week. Coverage expands across the syllabus as chapters are published, starting with the higher classes preparing for the public exam.
Tamil medium and English medium
Every published question exists in both Tamil and English. Use the EN / தமிழ் switch at the top of any page to move the whole site, including question stems, options and explanations, into the other language. The two versions live at separate addresses, so you can bookmark or share whichever one you study in.
