Hei Pradeep,
Try to find out how much time you need to study each knowledge area.
Depending on that, prepare a schedule and see how many days you need to complete your preparation.
I assume that you couldn't complete your first round of prep.
Which books are you studying?
There are few books out there, Headfirst PMP, Rita's, Andy etc.
You should read any two books and it seems one of them should be Rita's.
During your second round, you need to study PMBOK Guide.
Solve as many knowledge area wise questions as you can, from reputed sources.
Once you complete second round, start mock tests.
During mock tests, keep a track of time you are taking.
In my case, it happened that I could complete ALL my mock tests in 2.5 to 3 hours, whereas I took 3 hrs 40 mins in the real test. Pls keep this in mind.
DO NOT be in a hurry to give the test in 40 days.
It may so happen that 40 days is not sufficient, but a few more days, say another 10 days, will make you ready for the exam.
So, schedule the test only if you are very confident of clearing it.
Many people, who cleared their tests, have posted the LLs (Lessons Learned) in the forum. Go through them.
You may find them useful.
If you stay with your family, you need lot of self discipline.
Forget everything else. Going out in the evening, weekends etc.
Exam should be the only thing on your mind.
All the best for your prep and exam.
