The three types of TOEFL
Until 1998 everybody had to take the paper-based TOEFL test. It has three parts – listening comprehension, reading comprehension and grammar. Answers had to be marked with a pencil. The maximum score you could get in the TOEFL PBT was 677.
Computer based TOEFL
The computer based TOEFL test was introduced in 1998. The maximum points you can score in the TOEFL CBT is 300.
The TOEFL CBT has four sections – listening, grammar, reading and writing.
The listening comprehension and grammar tests are adaptive. That means the kind of questions you get depends upon your level of English. Just keep in mind that questions that are easy to answer carry less points.
You will know your TOEFL CBT score instantly. Official results are available in 14 days. Don’t rush through the questions. Remember that after you have given your answers, you can’t change them.
Internet based TOEFL
The internet based TOEFL (iBT) was introduced in 2005. It has four sections – listening, speaking, reading and writing. Note that the speaking test is not included in the paper based and computer based TOEFL.
There are integrated tasks in the TOEFL iBT. That means some of the questions require you to combine more than one skill. For example, sometimes you will have to read a question and then speak in response.
As you may have noticed, the TOEFL iBT doesn’t have a section on grammar.
