AP Credit

I scored a 4 on human geography exam 2017. Is it good to earn a credit in good colleges including Ivy or top public Universities??

Each college has their own AP credit policy available on their website so you can do a search on any schools of interest to determine if you will receive credit.

Here is a link for UCLA:

If an Ivy gives any credit for an AP exam, it will generally only be for a 5. Few, if any, Ivy League schools give credit for APHG. But as noted above, each school has its own credit policy, which are easily found via google.
