TOEFL is an English certificate which aims for academic use and is widely used around the world. The test form currently offered is an internet-based test (iBT) which can be taken in numerous test centres worldwide and takes about 4 hours. The grade of the test is equally combined out of the following four parts.

Each part is graded with up to 30 points which adds up to a maximum score of 120 points.

• Reading comprehension
• Listening Comprehension
• Speaking
• Written Expression

During the entire test, you are just interacting with a computer. In the first two parts, you read and hear texts about various topics and answer multiple-choice questions about the content later. In the speaking part, your spoken answer is recorded, sent to an online scoring network and evaluated by three to six raters later. The written part is evaluated by this online scoring network as well.

Unlike other English language proficiency tests, PTE Academic consists of a single 3-hour test session which includes three sections: speaking and writing (together), listening and reading. There are twenty different question formats, ranging from multiple choice through to essay writing and interpreting information.

The Graduate Record Examinations (GRE) is a standardized test that is an admissions requirement for most graduate schools in the United States. An admissions exam that measures the verbal reasoning, quantitative reasoning, critical thinking and analytical writing skills of candidates applying to graduate and business schools. Institutions use scores, along with other measures, to identify the best candidates for their programs, and for placement, program evaluation and selection of fellowship recipients.
The computer-based GRE General Test consists of six sections. The first section is always the analytical writing section involving separately timed issue and argument tasks. The next five sections consist of two verbal reasoning sections, two quantitative reasoning sections, and either an experimental or research section. These five sections may occur in any order. The experimental section does not count towards the final score but is not distinguished from the scored sections. Unlike the computer adaptive test before August 2011, the GRE General Test is a multistage test, where the examinee’s performance on earlier sections determines the difficulty of subsequent sections. This format allows the examined person to freely move back and forth between questions within each section, and the testing software allows the user to “mark” questions within each section for later review if time remains. The entire testing procedure lasts about 3 hours 45 minutes.

The Graduate Management Admission Test Is a computer adaptive test (CAT) intended to assess certain analytical, writing, quantitative, verbal, and reading skills in written English for use in admission to a graduate management program, such as an MBA
The GMAT exam consists of four sections: an analytical writing assessment, an integrated reasoning section, a quantitative section, and a verbal section. Total testing time is three hours and seven minutes. Test takers have 30 minutes for the analytical writing assessment and another 30 minutes to work through 12 questions, which often have multiple parts, on the integrated reasoning section and are given 62 minutes to work through 31 questions in the quantitative section and another 65 minutes to get through 36 questions in the verbal section.

The SAT has four sections: Reading, Writing and Language, Math (no calculator), and Math (calculator allowed). The test taker may optionally write an essay which, in that case, is the fifth test section. The total time for the scored portion of the SAT is three hours (or three hours and fifty minutes if the optional essay section is taken). Some test takers who are not taking the essay may also have a fifth section, which is used, at least in part, for the pretesting of questions that may appear on future administrations of the SAT. (These questions are not included in the computation of the SAT score.) Two section scores result from taking the SAT: Evidence-Based Reading and Writing, and Math. Section scores are reported on a scale of 200 to 800, and each section score is a multiple of ten. A total score for the SAT is calculated by adding the two section scores, resulting in total scores that range from 400 to 1600. There is no penalty for guessing on the SAT: scores are based on the number of questions answered correctly. In addition to the two section scores, three “test” scores on a scale of 10 to 40 are reported, one for each of Reading, Writing and Language, and Math. The essay, if taken, is scored separately from the two section scores
