Hi Vijay. 53 days is not a lot of time, but I don't think it's impossible to prepare in this time. You might want to look into taking a bootcamp style class, which is intended to prepare people for the exam in a very short period of time (it is typically one very intensive week of training). I think it is also possible to develop a rigorous study plan of your own and start immediately. However, another option is to simply postpone your exam. I can't speak for all testing centers, but I know my testing center allowed for date changes for a fee. Good luck to you in whatever path you choose!
