you want to take your dat in march (that way if you have to retake it you can do so and still have complete applications on file very early in the cycle. you have to wait 90 days between taking it the first time and registering for the second time. nobody wants to think they will have to retake, but its best to be prepared.) start asking for letters of rec around february, that gives the profs a good 4 months to write it and send it in. aadsas doesn't start collecting them until like may, so if you have very efficient profs you will want to ask them to hang onto it until may and then send it out. send away for your transcripts as soon as grades are back from spring semester, and when you recieve them, send them unopened to aadsas. start writing your personal statement over winter break, that way you'll have lots of time to sit down and work on it (in between studying for the dat). when you get back to school, have people read it and give you thoughts. then you can revise it whenever you have time up until it is time to send it in. another tip: print out a copy of the 2005 application while it is still posted. DO NOT fill it out online or send it in, just print out a copy or save a copy to your computer to look through. i would assume applications are quite similar from year to year, so this will give you an opportunity to read through it, get any questions you may have answered in between now and when the 2006 one comes out, and start giving thought to your answers for the short answers section. if you do everything i said in this post, barring some unforseen occurance, you will have a complete package on aadsas's desk on the first day possible (take it from someone whose aadsas number was less than 50
) this will be advantageous in many ways, 1) less chance of them losing or mixing up your stuff, 2) it will only take 4 weeks to process instead of 6 -8, 3) you will be the first to hear about interviews from schools 4) schools still have all their spots open when they consider you, you are not fighting lots of people for the last 10 spots. one last thing, check your schools' websites for what supplementary materials they want. for example some schools want you to send them a small photo, and all schools want their application fee!!
send these things directly to the school at the same time that you send your application in to aadsas.
wow, that was a long post. hope it helps all future applicants with their timeline, it worked for me
