A kid is better off studying the standard, high rigor “foreign language, history, literature, writing, 3 lab sciences, math to the highest level he/she is capable of” than doubling down on what the top ten business programs at universities will see as a less rigorous plan.
A kid does NOT need to be studying econ in HS! Better to ace Calc BC so he/she can hit the ground running in Econ at college!
