It looks like you are confused about the difference between Aptis and Toefl ibt. I would suggest you to look into the differences between them first. Then choose the one that best suits you.
Toefl ibt is usually given to college students who have been admitted into one of the graduate programs offered by a university. Students who need a TOEFL test to apply to other programs or for graduate school admission should use the official Toefl test. The Toefl test is given on the internet and consists of four sections: reading, listening, writing, and speaking.
Aptis is a test which is intended to be used to determine the English level of the examinee. However, the Aptis is an objective test, so that people with different levels of English can be compared on a consistent basis. The Aptis test includes four sections. These include listening, reading, writing and speaking.
Aptis is an international standardized test that is given to students in all countries in the world.
Toefl ibt is an international standardized test that is given to people who want to study in universities or colleges in many countries.
