Hello everyone! For students who need some practice with grammar such as getting down preteritos, imperfectos, subjuntivos, etc here is a website that can serve as great practice. You pick what you want to work on and you are given a paragraph with blank spaces for you to fill in the correct tense of the word. Then you can later verify how well you are progressing. Hope this can be great practice!!!  –  Belen
