I'm having trouble remembering the difference between Estar and Ser

Question

Hola, Is there any way I can get help besides taking quizzes here to understand the difference between Estar and Ser uses?

Answer

Hi Rozalyn
I am afraid there is no quick way to learn the difference between them. We set our lessons about these two very important verbs in a way that the students see in what specific situations/contexts one is used and not the other. This is because there isn't one single rule to differentiate them. 
If you click here and scroll down, you will see lots of our lessons about ser and estar, for different levels.
Ser and estar
Saludos
