TOEFL iBT Test Prep Centres
TOEFL classes offered by specialized Exam or Test Preparation Centres are designed with only one purpose in mind: to help you get the highest score possible on your exam. Theoretically, this would imply that they are the best places to prepare yourself for the TOEFL. In reality, this may or may not be true. As in any buying decision, you need to do some investigation and research before handing over your money.
TOEFL preparation centres vary widely. They may be international chains or local schools. They could boast thousands of successful graduates or just a few. The instructors may be exam preparation specialists or general ESL teachers. The schools may produce and sell their own books and materials or use existing test preparation books and software. They may offer a guarantee, based on your success in the exam, or not. It's best to ask the school about all these elements before signing up and again, attend a free class, whenever possible.
Sometimes, test preparation centres offer short, focused, intensive workshops and seminars, which can also be extremely helpful. These are generally held in the evenings or on weekends.
Most important, remember that as a student, you are a consumer and deserve to have high quality training, but you are also the one responsible for making wise buying decisions.
