Made a mistake!

I am international student and I made a mistake on my Common Application and listed my GPA (Weighed) as 7.9 on a 7 Scale whereas it is actually 7.76. Should I inform the universities of this mistake or let this go as it is? Applied to a few Ivys and Liberal arts colleges. I would really be grateful for advice!

Yes, you should notify them. Email admissions with the correction.
