Question

For SPANISH SPEAKERS :

Are these sentences correct? Because I don’t know if I used the right preterite or imperfect forms. Please recheck.

Answer 1

2.cuando era joven era amable. una vez ayude a mi hermana
3.Cuando era joven era graciosa. una ves me puse el vestido de mama

Answer 2

I do speak Spanish but how do you want to put the sentences?, is that I read it over and over again and it doesn't make sense
