To mean, "you are correct", we sometimes say:
you got it right!
you've got it right! (used in BrE, not sure about AE)
you've gotten it right! (used in AE??)
Are they all correct? Are they simple past and present perfect forms of the verb "to get"?
I ask this because the verb "get" is sometimes very confusing, and on a number of occasions, its past form "got" is interchangeably used with the verb "have" or "have got", especially in AE, as in, "I got this" and "I've got this", both meaning "I can/will do it" (or I have =have got=got a car). As can be seen, in this usage, the verb "got" ceases to have any past meaning, and refers either to the present or future. My question is whether "got" in sentence (1) above has this non-past meaning, or it is simply the past tense form of "get", which means (1) is in past tense and (2) and (3) are in present perfect tense.
