B5 is a pretty good upper range for a choir soprano or a mezzosoprano, almost an octave above tenor high C (which is C5).
Yet you are asking about chest voice range. That alone will likely limit the usefulness of an answer to you.
The problem with "genetic potential" is that this does not tell you anything about sustainable and musically useful range and what that B4 (which I assume you have meant to be writing) actually means in that context is not likely to be known to readers of this group than it will be to your vocal teacher. If anybody, you should be asking her or him. And if that does not result in an answer you are satisfied with, it is extremely unlikely that you'll get a more useful answer from people who never heard you sing, nor participated in your vocal development so far.
At any rate, after 3 months of lessons it is certainly too early to apply for a singing scholarship or sign contracts for musical or opera singing, so there is little point in fixing a target tessitura right now.
