It's the fat ration fella from Jakku I think. You only see a flabby arm.
Nothing in SW canon can explain her speed of picking up the abilities. Especially not dark side of the force abilities (reverse mind probing/reading).
Around 10 years prior to the events of TFA. She was left with Unkhar at the age of 6-8. She's around 18-19 in TFA.
JJ confirmed in one of the interviews that in-story timeline between OT and TFA is 38 years. More than enough for Ray to be Luke's granddaughter if needed (yeah, I'm still pushing this theory) ...

No course required eh? So what was the whole Jedi academy and the Sith apprentice scheme all about?
Nope, not even luke learning how to deflect blaster bolts blind in seconds from just being told to use the force. /end sarcasm.
Sith apprentice scheme? So you think Palpatine did a lot of classes with Vader on how to use Force Lightning? Please.
WThe simple answer is we don't know. At no point do we see training actually happen. How often do you see Obi Wan teaching Anakin how to use the force? Most of his training seems to be moral training on how to deal with the different challenges facing a jedi, from resolving diplomatic conflicts and the like.
I've cracked it!
Yoda said "try not; Do, there is no try"
Rey simply just do, soon she realised she has the force "repell mind reading", she just do!
Ta da!
