There are no cat sample question papers... please upload the sample and solved Cat papers please

If you will.go through the careers360 app you will find that some of the question papers are already uploaded as a sample which you can attempt it. Also on Google search you can get a few previous years CAT papers with solutions. If they are very old papers then I don't recommend you to attend it because they must be of totally different pattern and you won't be able to come up with a proper strategy to tackle the real paper.

There are few sites like http://www.hitbullseye.com/courses.php where you can sign in and attempt lots of online mock for free.

Make sure you go through this site it has lots of mock test and with test it provides in-depth solution and analysis of your score. Also the paper is exactly in the same pattern as of final CAT exam. You can also expect the level of questions also to be similar as of CAT exam.

Not only this on Google search you can find lots of free online mock test paper. Try to attempt and analyse as many paper as you want to improve your score.

All the best!!
