Vaishnavie,

(It doesn't work yet) but it'll tell you how much money you should have at the end of each week and also how much you should spend per day depending on the size (it assumes you use all your money) but generally you divide by 225 school days. (so about $10 a day)
As for the difficulty to use your money, it really depends on how much you eat/what you eat/if you only eat on campus. Generally, I find it pretty easy to finish the basic portion. I spend my money on lunch & dinner about 5/7 days a week (I make my own breakfast). I rarely buy drinks on campus (1-2 times a week), and rarely will cook my own food/bring in something from home. I usually finish my basic on the exact last day. I also sometimes buy treats (chocolate, cupcakes, cake etc.) which tends to be pretty expensive (about once a week and more during exam time/midterm time)
Just a reminder that you need to request to get the $ back, it doesn't just end up in your account at the end of the year.
