Hello, people of kaskus .
I have a problem, a huge problem .
I have decent knowledge about vocabulary, but i really bad at tenses, i don't know what tenses to use, sometime i rely on my hobby, which is watching Youtubers (that speak english, ofc ) & movies, so i just remember the line the Youtuber/Actor/Actress have said .
the reason i consider that as a problem, is that in 4 months, i want to be a student on a college that requires a English test, that consists of tenses, error recognition .
That being said, I want to improve my knowledge on tenses, i have tried before, but i forget it after 1-2 weeks,
what the easiest & the most efficient way to become a expert on tenses?
