hi is it worth memorizing a bunch of sat words until march or should I just learn the prefixes and suffixes?

Now that I know I will have to take the March SAT, where and how should i start studying? Idk if it'll be possible to earn above 1400 by March but I didn't really study for this sat at all. Should i just start taking practice tests or should I learn desmos strategies? I know there's a program here for sat prep but what else am I supposed to do, especially if I'm not getting tutoring or classes?
