You can even refer different online sites for such paper as we dont have its papers at present but its quite easy paper to solve if you are preparing well for jee than its easy for you.
Unfortunately COMEDK previous year papers are not available like that. Instead you could check out the KCET question papers. The other alternative is to check the various coaching centres if they have put it up though I doubt it. The syllabus is kind of same for KCET and COMEDK so you can actually use them for pactice purposes.
