Question:
What to do if you missed mincha?
Answer:
It depends on the reason why you missed it. If it can be considered an accident, then you can daven maariv twice. After davenng Shemona Esrei of Maariv, daven a second Shemona Esrei as a makeup one for the mincha that you missed. After that say Aleinu
If however you're missing it was purposeful then it cannot be made up.
Best wishes
