English 4: Learning english

It's easy for me to learn english memorising estructures and applying it while I talk with someone else about any topic.
It's hard for me to learn when I am not interested in the class or when I'm not sure about the teacher skills.
Something I want to learn in this course is how to use more complex verb tenses.
I learn better in classes where the teacher is clear about the contents and instructions. Also when I can practice.
I participate more in classes when the topic of conversation is interesting.
