Every hole has 4 objectives:
-Completing the hole under par
-Collecting all the gold coins
-Collecting the weapon crate
-Earning enough skill points for the 1up.
The easiest hole to get this on is Britannia one as it is an easy hole to get under par, has 20 easy to reach gold coins, the weapon crate will come along with the coins and you only need 10,000 skill points which you will get from being under par.
Note: You do not need to do all of these at once, you can get under par and then retry and go back for the coins and crate, and can get the coins on multiple runs.
