Well the site and app both are useful in searching college or compair between different collages and is also useful as a reference any other material required to study.But after registration it starts sending you endless message on the topics which you didn’t subscribed and starts sending notification which it’s irritating and I personally don’t like it.So if you want to try you can do but you will be trapped in endless cycle of speak message.Remember to take your time while deciding as it is about your future. So sometime spams also does not matter.
