By all means, she should go for the 22k.
And, please have her keep in mind, while she is breaking her head to get good grades at this 22k sem, the bocher she we will most likely date (upon her return) probably went to EY for not much more than dira gelt, and $ for bein hazmanim trips.
Oh, and once she gets back, she (and your parents) will also need to promise $$$ in support for the privilige to marry this character.
Great system we have made for ourslelves, no?
