Everything seems to be planned, especially now that she has her results. She is going to study, then work as a lawyer, marry some good indian boy, have children with him.

the "going to" covers all the verbs that follow, so they need to be in the infinitive.

ahhh, okay! Thank you very much! :D

Schaut komisch aus. Braucht nicht das "then" zumindest noch ein "to" danach, damit das grammatikalisch richtig ist ?

I have a problem with "planned." I would say "planned out" or "set."

"Indian" needs to be capitalized.

So four changes:
Everything seems to be SET, especially now that she has her results. She is going to study, then work as a lawyer, marry some NICE Indian boy, AND have children with him.
