From California and I ended up deciding to apply without my spring quarter grades because it would not significantly change my GPA. An added benefit to not waiting for your spring quarter grades is that if you do well, you can use it to update schools later on down the line.
You must also take into account the time that it takes AMCAS to actually receive your transcript because without an official transcript they will not process your primary application. Worst case scenario is that you would be able to send your transcript to AMCAS around late-June, it would then about a week to arrive at AMCAS, and perhaps up to 6 weeks for them to process your transcript. For this reason I decided to send my transcript ahead of time with only up to my winter quarter grades so that when I submitted my primary application everything would be ready to be verified.
As a timeline reference, I had my official transcript at AMCAS in May and primary submitted by mid-June and it still took 2 weeks to be verified.
