my rank in kcet 1,65,000 can I get seat in pesce mandya for mechanical engineering...

With a KCET rank of 1,65,000, getting Mechanical Engineering at PES College of Engineering, Mandya is very unlikely in the earlier rounds. In recent years, the cutoff for Mechanical has usually closed around 1,30,000 to 1,40,000 in Round 1, and in some cases extended beyond 1,60,000 in Round 2 or casual vacancy rounds, depending on the category and seat availability.

If you're from a reserved category, you might still have a chance in later rounds. Otherwise, the chances are slim. You can wait for further rounds or explore other colleges where the closing rank for Mechanical is higher.
