A-License Shortest feasible time

Hi Folks,

When you got the A license, what was the time that you finished. If weather permits, is it feasible to finish in 14 days. Or would one need upto a month.

I have plans to do the course at Thai Sky adventures. I only have a window of 21 days from 16th December to 5th January.

Will 15 -20 days suffice. Challenge is Christmas and New Year are part of these days
