Have you been taking TOEFL practice tests? Are you sure you’re prepared for the experience of taking the real thing? Many students think so, but they are actually making terrible mistakes during test prep. The TOEFL English test is a high-stakes, high-stress exam. It can make the difference between dream college acceptance and career success, versus a lifetime of regret.
# of passages and questions
||20 minutes for each 700-word passage and associated questions
Or, about 1.5 minutes for each question—including reading time.
||60-90 minutes for the lectures
60-90 minutes for the conversations
Or, about 2 minutes for each lecture question, and 5.5 minutes for each conversation question, after listening is done.
||15-30 seconds preparation time for each task
60 seconds response time for each task
||50 minutes for both, minus 5 minutes for reading and listening in first task.

Many students struggle with the speaking section during TOEFL iBT practice. It can be very hard to speak for 60 seconds in a structured way, especially when you are having a one-way conversation with a microphone instead of a real person. To prepare for this, you need to practice until it is practically second nature to speak about any topic for 60 seconds at a time.
The 1-Minute Argument method is an easy and effective way to chip away at this problem, piece-by-piece, until it’s totally gone. What you need to do, at least five times a day, is speak for 60 seconds at a time—to a computer, a wall or your pet—and create a structured argument for or against something. For example, if you see something on the news you disagree with, grab your cat and speak for 60 seconds. Start with an introduction where you state your belief, then provide 2-3 reasons or facts that support your belief and why, and then summarize yourself with a conclusion. If you have a 1-Minute argument, 5 times a day, you will be able to ace the speaking section on the TOEFL iBT.
I adapted this method from ETS, which recommends practicing 1-minute responses as a key part of TOEFL iBT practice.
