This all depends on the individual. For me PL/SQL was a living hell, I failed it twice. Prior to that I had no programming experience so that is one reason. I did have Oracle installed at home and practiced my butt off each time I took it.

Oddly enough as hard as Perf. Tun. was it was that exam that I scored highest on, I was surprised!

So, my vote is get pl/sql out of the way, but be afraid, be very afraid. Bwoo ha ha ha harrrrrrrrrrr
