Hi Richa, you can find mock test papers published by board of studies of ICAI for our practise. Just visit icai.org and in BOS knowledge portal, you will see model/mock test papers. Select final and select respective subjects for which you need test papers. You can also find the seperate solutions for them there. Icai publishes 2 test papers per subject before every exams. You will also find seperate solution sets for each test papers. I am sure this will serve your purpose. You can check these mock test papers for 1st groups @ http://www.caclubindia.com/forum/mock-test-papers-for-ca-final-grp-1-241525.asp#.UUjO5xeBms0

Good luck for exams.
