my first year at U of T in the astrophysics program (1989) I was paying about $1900 for a full year's tuition. The whole year including staying in residence, food plan, and books,etc cost me about $7000. That even included my spending $$ and travel to and from Northern Ontario to Toronto about 3 times.
Right now, the tuition for one year of the same program is $5000 JUST for the tutition! Cost of living, apartments/residence/meal plans/books/etc has gone up.
I know kids who are paying $10K to $20K a year for school. Thats nuts... I am glad I graduated when I did (3 years University, three years college alldown south and I had only $24,000 in dept when I graduated - I did work summers too)
