Hello aspirant,

Hope you are doing great. In your question, you didn't mention the name of the intermediate board, so, from your profile, I assumed that you are from Andhra Pradesh. And further, you are from 11th standard. See, the pre final papers won't be available anywhere, however I'm providing you the link for sample papers and also previous year question papers for all subjects for 11th standard. Also, most probably you will get questions from these papers only. So, Check this following link for the pdfs:

Hope this helps you.

Thank you :)
