Hello, 

It is good to know that you have completed the preparation as well as previous years tests. In case you haven't done it, you can go for correcting your mistakes in all the tests you have attempted. Coming to the question,it is very important to go for mock tests(for entire syllabus) , because they are generally tougher than the ones that you solved in previous years papers. So go for mock tests or grand tests that are available online. But revising the short notes you have made yourself is also important, so allot time in a day for yourself for both revising as well as doing the test. Revising and tests are equally inportant.

Hope this helps you ....
