Good to know

Where do these papers come from?: From the question papers and answer keys Kerala PSC publishes after each exam. Every page links to the official PDFs, and answers follow the official key. Read how we check content.
What is the difference between the provisional and final key?: Kerala PSC first publishes a provisional key and invites complaints. After reviewing them it publishes the final key, which is the one used for marks. A paper marked “Final answer key” has the settled answers.
How should I use old papers?: Solve one paper for your post as a mock test to see where you stand, then go through the explanations of the questions you got wrong. Papers for the same post repeat topics and question styles. Check the syllabus to see what else is asked.
