VPN to access University materials

I used a VPN and set my IP to a foreign country whilst accessing University materials. I did this to test the procedures that exist if they detect a login from overseas. It blocked my login because it flagged it as suspicious, and I had to contact IT to get it unblocked.

When I am actually overseas, will a VPN make it look like I am in my home country of choice, or will they be able to track me further?
