I really wanna do MS in CS from ASU in the future. I just finished school and have no idea where to begin. like what should i focus on from now itself? and when is the asu ms cs deadline usually?
It’s noce that you are thinking about it this early 
You’ll need a good cs undergrad first (btech, bsc, etc), aim for decent cgpa. also keep ur maths and coding strong from now itself – python, dsa, stuff like that. ASU’s super competitive lately so plan ahead.
