Solution to the dilemma
I must confess that, this dilemma of Jack is genuine and is tough to provide the correct solution. What makes this situation really tough is his GMAT-score 610.
Jack still has plenty of time (may be couple of more years) before he would apply to b-school.
610 is critical score, an ‘on-the-wall’ score you can say; which is not a good score but given a chance, with proper study strategy, he can improve his score to a respected level
610+40=650! which is at least an average score for decent business schools. But note that it could go really tough for Jack to improve his score by more than 40. Therefore, I call 610 as a critical score. Anything less and I would not advice Jack to retake the test. Remember, you cant fool this GMAT test.
