It is a paid service provided by ETS, a TOEFL publishing agency. Every time you apply for TOEFL, a TPO service will be attached, as long as you use it in the TOEFL registration account. All TPOs are the original questions of TOEFL, and every paid TPO service will get official feedback from TOEFL. You need to be online to use it.
TPO is a fully simulated TOEFL iBT (internet-based test) platform, which is aimed at people who take the next generation TOEFL test (online TOEFL test) and students who want to improve their professional English. TPO is a real question that ETS has tested before, which is of great value to candidates' mock review before the exam.
The function of TPO is to simulate the exam. Candidates can use it to understand the real questions, be familiar with the examination environment and operation, and test their real level before the exam. You can rely on the internet and follow the tips on your home computer to complete TPO independently.
Extended data:
There are 33 sets of TPO (constantly updated). ETS will decrypt some TPO through various channels from time to time, but these questions are no longer tested.
TPO requires the computer to be equipped with headphones with microphone, stable network connection and bandwidth above1m..
Relatively speaking, computers with fast network speed are not prone to interruption or lag, and the model test effect is good. Therefore, it is suggested that the model test be carried out in the place with fast network speed.

The exam takes the form of a computer exam. The test time and the number of questions in each part of the new TOEFL are fixed.
