415 - 615 in under 30 days

Hello,

I know the subject line sounds shocking but I want to know if I can score a 615 - 645 on the Gmat Focus in under 30 days?

My last official mock score was 415 with minimal prep, a few months back as i have postponed my gmat twice because of some reasons.

I dont want to spend more in rescheduling and if i do reschedule i wont make it to R1 deadlines of my application, So, i have started studying, averaging about 6 hrs per day from the last 3 days,

To sum up, I just wanted a realistic answer to my question,

Any help will be much appreciated.
