New TOEFL Generation

Nowadays, we have a new TOEFL. It is Internet Based Test (IBT) TOEFL. It is so different than the old TOEFL (Paper Based Test TOEFL). When the old one still used three section, first section was Listening Comprehension, the second section was Structure and Written Expression (SWE), and the last  section was about Reading Comprehension, the IBT TOEFL uses the first section is Reading Comprehension Skill but we don't look at the reading text but we just listen to the text then we answer the question, then the second section is about Listening Comprehension then the last section is about Writing. It is so different from the PBT TOEFL. We don't study again about Grammar. But how about if the students are still weak about Grammar, is it a problem? So to make you better in grammar before studying TOEFL, you should follow the Pre TOEFL lesson.
