Vocabulary is the hardest part.Reading and writing are ok,no listening part.Last around 3 hours.If you can pass it,hopeful you can enter the university to study acdamic not language courses.
Good luck!
If you can pass it,why do they ask you to study ESL?I think this ESL should be university courses,not continue education.Yeah,vocabulary is just like what you guess.If your writing can over 3 out of 5,even you just get 280 out of 500 on the rest,you still can pass.
