No one can predict what you can get or what may come in questions. Yes, it is great that you are getting 450+ in your Mock test. It means that you have completed your syllabus and working on your mistakes.

Just one suggestion for you, do not start anything new and try to rectify the mistakes you are making in your mock before appearing for another mock.

Work hard on your Forte!!!

All the best, you can even get 570+.
