About 12th Standard practice tests
These 12th Standard online tests follow the Tamil Nadu State Board (Samacheer Kalvi) syllabus. Select a subject above to open its units and chapters, then start a chapter test. Every question is available in Tamil and English medium, and each answer is graded on our server so your score is accurate.
The 12th Standard public exam paper opens with a one-mark objective section. Practising those multiple-choice questions chapter by chapter is one of the quickest, most reliable ways to lift your total — and it is exactly what this page is built for.
What you’ll practise
Each chapter test is drawn from that chapter’s pool of book-back and one-mark multiple-choice questions. You choose how many questions to attempt, answer them, and see your result straight away — with the correct option and a step-by-step explanation for every question, so you learn the method rather than just memorising an answer. You can come back to retake any chapter and reinforce a topic that still feels shaky.
How to get the most out of it
Work through one chapter at a time instead of jumping around, and read the explanation after every question — even the ones you got right. Revisit any chapter where your score was low, and closer to the exam attempt whole chapters in a single sitting to build speed and confidence under exam-like conditions. Short, regular sessions beat occasional long ones.
