Typically turboprop training tends to be a little more difficult versus CRJ or ERJ.
Regional training consists of INDOC (rules, procedures), Systems (hydraulic, powerplant, avionics), CBT or ground trainer for flows and finally the simulator. Memory items and limitations will be memorized before starting class.
Total initial training time is about 8 weeks. You will study about 2-4 hours a night, depending on how quickly you absorb the material. Based on people I have talked to, if you possess a good attitude, study like crazy, the airline will give you enough training to pass the checkride.
