Question

Use an appropriate form of ir+a+ infinitive. Rewrite the sentences.
Nosotras asistimos a clase hoy
Am i doing this right?
Nosotras vamos asistir a clase hoy.

Answer 1

You're missing an "a". It should be "Nosotras vamos a asistir a clase hoy". Notice that in the instruction you've been given it says "ir" which when you conjugated is "vamos", then "a" which is "to" and then the infinitive form... That's the "a" you're missing.

Answer 2

Claudia07 is correct. You should to replace "asistimos" with "vamos (form of ir) + a + asistir (infinitive)" = "vamos a asistir" :)
