"That was going to be her last semester."

Translation: Ça allait être son dernier semestre.

[dapetras]

how come 'dernier' comes in front of 'semestre' here?

[ferynn]

"Counting" adjectives are always before the noun they go with.

Is c'allait an option?

[n6zs]

I think it is possible...but I don't know how "proper" it is. Ex: Ç'allait être ma meilleure histoire! = That was going to be my best story yet! http://dictionnaire.reverso.net/francais-anglais/c%27allait
