Adding points from one sheet to another

Hello,

I'm trying to record points that students accumulate in a club.

In a GoogleForm, I check off the students (Estudiantes) that earned x points (# de puntos) and also indicate what event they earned the point at (Nombre del evento). That goes to "Form Responses 1".

Now, in "Form Responses 2" I want to be able to see the number of points that particular student has and the name of the event where they earned the point(s). But the students are listed among many different student names in the "Estudiantes" column of "Form Responses 1".

I imagine this involves an IF formula, but I imagine it involves so much more, too and I'm totally lost. Images below!

Any help? THANK YOU SO SO MUCH.
