What will be my gpa?

No idea.  We would need to know how many classes/hours are included in that 3.71.  To get your AVERAGE you must know the denominator, not just the numerator,

It really depends on how many other classes you have taken, the more credits you have, the less these credits will move your gpa, remember gpa is a weighted average of all your grades, I suggest either talking to a counselor or calculate what it would be by hand (it’s really easy, just look it up, it’s hard to explain on an answer)

I would speak to your guidance counselor and try to score for A’s
