I have 660 gmat 3 years work exp

I got into clark university full time mba program ( 40% scholarship)
I also got into uc denver
Should i attend?

Probably not. With a 660 GMAT you could get into a much better school, especially with a year's extra experience, and the added lifetime value of a better school would be into the hundreds of thousands or millions. Read the posts linked from my profile page on GMAT Tiers and The sad facts about scholarships.

What do you think about depaul , university of Cincinnati and virginia tech??

I have around 3.5 years. I need to get in the spring intake 19.

Clark's average GMAT is over 100 points lower. UC Denver has just 80% employment. You can do much better.

Im constrained by the spring intake
