Community colleges in NYC ? how to make it happen to other universities ?

Okay so i am about to get 18 in January and gonna join BMCC [NYC], i know its kinda late .

So i have few question . Is it hard to get job with an associate degree ?

Can i be transferred to UCLA[Out of state [ny]] or any other , instead of CUNNY OR SUNNY ?

Can i give SAT Again and Get my bachelors degree after completing my 2 years college at community College ?

starting Bachelors at 20 will make any difference ?
