験 test

I'll test my gambling expertise by risking it all on that hose. I mean horse.

experience ★★★★☆
経 (experience) + 験 (test) = 経験 (experience)

an experience

a scientific experiment ★★★☆☆
実 (truth) + 験 (test) = 実験 (a scientific experiment)

test ★★☆☆☆ NP
試 (attempt to do) + 験 (test) = 試験 (test)

a test, like in school - kind of formal. (BOOBOO : normally people just say テスト)
