Hello sir, I’m preparing for Rajasthan Pre-Entrance Test. For this Rajasthan Pre-Entrance Test I want last year question papers please provide me?

[Rajkumar Agarwal]

The Rajasthan Pre-Entrance Test is conducted by Rajasthan Technical University for admission into various courses such as engineering, pharmacy and architecture.

This examination will be conducted somewhere towards the end of month of May.
