Then lock yourself in a room and study! (Geez… I can’t even imagine doing that to myself…)
Do remember that board scores aren’t everything – for some uber-competitive ones, yes, they’re very important, but they aren’t the whole package.
Also, keep in mind that if you do well in 3rd year, it’s quite possible to raise your Step 2 score dramatically over Step 1. (I worked my tail off in 3rd year, and ended up improving my average Step 1 (216) to a whopping 245 on Step 2. Step 2 is much more clinical, and you actually learn it as you go – so that you won’t need to dedicate near as much time to prep.)
PS. And try not to freak out while shooting for that 230. It can certainly be done… just remember that the average is in the teens, so half of people score below that. We tend to lose track of this, being such competitive people.
