Cal Poly Pomona Provisional Acceptance! Need Help & Advice!

A few days back I received an email from CPP notifying me that I was provisionally admitted, however, they want to me to pay the security deposit by June 15th and mail my transcripts from the university (CSUDH) and college (Mt. SAC) I attended for the last 2 years by June 30th. The 1st problem is that I do not know if my final grades will be released in time before the deadline of June 30th because my semester does not end till the 18th for Mt. SAC. The 2nd problem is that I am short 3-4 units, but registered for US Hist for the summer. So, basically what are my chances of actually being admitted? Should actually pay the security deposit? And, thank you!

if cpp is your first choice then just pay it. $150 is not a big deal. and then just wait and see what happens
