Q5.37: Jack is a bright young investment analyst looking to attend a top private graduate business school in the evenings. His employer is willing to pay his entire tuition for up to two classes a semester after he completes the course and submits his grades. Being the crafty type, he devises a strategy to pay for his tuition on a rewards credit card immediately after a billing cycle ends to gain close to a two-month grace period, which he hopes to use to subsidize the remaining semester's interest cost with a cash back reward. He has a stellar 810 credit score. What could be an issue with his strategy? A Rewards cards typically do not offer a grace period. B Some vendors may charge a convenience fee of 2 - 4% for paying large bills with a credit card. Rewards cards typically carry a higher interest rate up to 29%. Rewards cards typically payout less points for higher purchase amounts
