Hi friends

Hi, I am very bad at learning English and I need to achieve\reach B1 for Cambridge because my boss wants me to have it. Please, I work in a bank as a cashier and I would like to get a Cambridge certification  but my level is very low and I think I need to* study a lot.

*¿Está diciendo que necesita estudiar inglés más? Entonces "and I think I need to study a lot" O talvez, está diciendo que ya está estudiando muchísimo? Entonces "and I already study a lot"
