TOEFL REVIEW is very popular method to pass and get a target score. Here is one of my suggestion to those who need to pass their exams. It is better to have a review before your target exam date.
Whether online or onsite review is an advantage. However, preparation is a must so a concentration is really important. I mean, if you have duty or work then you will have your review, it is better to enroll in a review center that offers flexible schedule which you can manage and plan your remaining time in a useful way.
