Help!!!!!! trouble with the Law?

ok so im 17 i got aressed this summer with +30 counts of burglary to cars and one garage that got dropped from a AG Burg to a residental 7. I know im dumb stupid ive learn my lesson THANK GOD they tried me as a kid, im not going to give out alot of details for my case safety i have a really good attorney 3rd ranked in my state and use to be the former D.A for my state and i got all those counts dropped down to 4 and my attorney and i made a plea bargain since i pled gulty to those 4 for probation and i was lookin at 1500 day but got it down to 28 but the state and the D.A said probation would be fine so my attorney and i are pretty sure im getting probation but im not getting my hopes up. " BTW ive never been in trouble befor i got a clean rap sheet and im doing good with my bond officer if i get probation how long do you think it would be ? your thoughts even though it's kind of hard what predict ( my sentencing is 51 days from now)
