Ashtanga Vinyasa practitioners: how long did it take you to accomplish the first series?

Hi. From those who practice Ashtanga yoga, I am interested in finding out how long did it take you to accomplish/master the first series. I am a rower in college and am on summer break for the next 13 weeks. During this time, in addition to weight training 6 days a week, I will be teaching myself how to do this type of yoga and am interested in finding out/predicting how far I will be able to get in this time period. I plan on practicing each day for 1-2 hours. Thanks for all the help.
