BSNL JTO Solved Question Papers

I applied for the BSNL JTO Tech Assisstant. I am fully prepared for the exam. I want to solve the question papers to know level of my preparation. Can you please share the old question papers for the BSNL JTO Tech Assisstant exam or tell me about the web site from where I can get them?

I am planning to apply for the Bharat Sanchar Nigam Ltd (BSNL) JTO exam searching for question papers for preparation. Will you please provide me BSNL JTO Solved Question Papers so that I can prepare well for exam also provide me along with BSNL JTO pattern of exam?
