1.5 (3) mile run time's decent, good, or bad?

1.5 miles in 10mins.

2nd 1.5 miles in 12mins. (started running and timing after 3 mins)

22mins for 3 miles, with delay its 25mins.

I'm preparing myself for the marines IST, I still of course, have to get my 15 college credits but I figure starting early would help.
