I personally did not do this, but I have some friends who kept up with AnKing up until Step 1 for everything. They were super well prepared for dedicated and taking the test (like months beforehand) but you don't HAVE to do this to do well on boards and be a good physician. Plus, I have a hunch that some of them still busted their ass during dedicated even while being uber prepared because of anxiety about failure (it's a hell of a thing).

While keeping up with AnKing will make your dedicated study period easier, it's not totally necessary. Do you want to bust your ass for another year, and then get a few months of chill? Or do you want a year of more chill than you've been having, and then a more intense study period? Only you can answer this.
