It also depends a lot on how much time you're willing to spend on your reps, how efficient you are when doing them, how motivated you are and if you're good at remembering things or not.
You have people like Kiara that are able to reach that point in a few months and be able to have a conversational level in a single year (people like her are usually the exception though, since she was VERY motivated), and you have other people for which it takes much longer than that.
