Getting one stat to SS rank gives you more points than getting 2 stats to A rank, so you want to hyper focus on raising a single stat.
You can also not use any of your skill points unless you have max level discounts on them and save them until the very end of the run to maximize the discounts you can get for those skills so you can get more skills for more ranking points.
Doing all of those could potentially brick your run though.
