7.69

This year, the lowest score to enter college is 7.69.  

In my opinion, if the person decides to and can learn something which interests him in college, 7.69 will be a lucky number for him/her.  However, if he/she doesn't know what going to college is for and decides to fool around in the following four years, it will be a curse for him because he will waste four very important years in his life.
