A good test prep company should be honest about what official materials can do. ETS writes the TOEFL, so official ETS questions have a real place in preparation. They help students understand the tone of the exam, the timing, the level of difficulty, and the way the test maker thinks.
If a student has never seen the TOEFL before, official material is a sensible first stop. I would never tell someone to ignore it.
But I also do not want students to treat officialness as a kind of magic. After a certain point, the question is not whether you have seen enough official questions. The question is whether you have practiced enough to change how you read, listen, speak, and write under pressure.
There is a point where the official pool stops being enough
This is the part I care about most. A finite set of official questions is valuable, but it is still finite. If you reuse the same material too often, you start remembering the answer, the passage, the audio, or the sentence. At that point, you are partly practicing memory.
That is not the same as getting better.
A student who struggles with speaking needs more chances to speak. A student who struggles with sentence control needs more sentences. A student who panics during listening needs more listening. A student who writes stiff, unnatural email responses needs more attempts, more feedback, and more chances to fix the same mistake until it stops appearing.
This is where official material reaches its limit. It can show you the exam. It cannot always give you the volume of practice you need.
That is the reason PrepEx exists
PrepEx is a practice platform first. That is the clearest way I know to describe us.
We are building a place where students can drill. Reading, listening, speaking, writing, full tests, smaller exercises, new TOEFL 2026 task types, awkward first attempts, cleaner second attempts, and the fifth attempt where something finally starts to feel natural.
Some students learn well through books. Some learn best with a tutor. Some need a structured course. Those are all real paths. But there is a large group of students who improve because they do the work again and again. They need a serious place to practice, and they need enough material that practice does not run out after a few sessions.
Those are the students we are trying to serve.
Our teachers and content team are a big part of that promise
I am proud of our teachers, writers, and content contributors. I want students to know that. PrepEx is a product, but it is also the work of people who care about whether a question trains the right skill.
We care whether a distractor is plausible. We care whether a speaking prompt sounds like something a student might be asked. We care whether a writing task rewards real control of English, not tricks. We care whether the content reflects the current test instead of an older version of the exam.
Most of all, we care that practice does not waste a student's time.
That matters because a practice platform is only as good as its questions. More practice is not helpful if the practice is careless. More feedback is not helpful if the feedback points students in the wrong direction. The human judgment behind the material matters, and it will continue to matter as we build.
I do not think students should have to choose one world
My honest advice is simple. Use official ETS resources to understand the test and check your direction. Use PrepEx when you need more chances to practice.
If official questions help you feel grounded, use them. If PrepEx gives you the repetitions you need, use us. A good study plan can include both.
We are not ETS, and we should not pretend to be. Our job is different. Our job is to give students a serious place to do the work after they understand what the test is asking of them.
Who we are for
PrepEx is for students who learn by practicing. If you are willing to drill, we can serve you well. If you want more attempts, more questions, more speaking reps, more writing reps, and more feedback loops, that is the product we are building.
Official ETS questions are important. They are not endless. Past a certain point, improvement comes from repetition, correction, stamina, and the confidence that grows when a difficult task becomes familiar.
That is the work we want to support.
