Hii Shahid!

There is no such sure shot method to get the error free previous year question papers for AMU class 11 entrance examination. Let me tell you that you can check for the sample papers on the official AMU website. Or, to go out of the way, you can visit the AMU campus. Near library you will find a Xerox shop. The shop keeps all previous year question papers. If you can't visit the campus, you can download an app called AMU entrance papers from Google Play Store.

Hope this helps.

Good luck!
