The Reality of TOEFL Preparation: Is a Classroom Necessary?
When I first decided to take the TOEFL iBT, the overwhelming consensus online was that you had to enroll in a massive, expensive academy like Hackers to get anywhere near an 80+ score. I remember walking into a counseling session at a crowded center in Gangnam, feeling like I was just another number in their revenue stream. They promised a structured curriculum, but after actually going through the process, I realized the ‘structure’ was just a standardized pace that didn’t account for my personal gaps in listening.
In real situations, this tends to happen: you sign up for an intensive, month-long course costing between 400,000 to 700,000 KRW, expecting magic. But the reality? You end up spending three hours commuting back and forth, only to spend another four hours in a lecture hall where you have little time to actually practice speaking. This is where many people get it wrong—they equate ‘attending’ with ‘learning.’ I spent two months in a physical class, and my score barely moved because I wasn’t doing the deep work of reviewing my own mistakes in the writing section.
Comparing self-study to online classes is the trade-off most of us face. Online courses, whether from Hackers or other platforms, typically cost about 100,000 to 200,000 KRW for a multi-month pass. The advantage is flexibility. You can pause, rewind, and focus on the TOEFL iBT practice tests that actually challenge you. The failure case here is simple: if you lack discipline, you will definitely fail to complete the course, turning that ‘0-won pass’ into a complete waste of money. I’ve seen peers buy those lifetime-access packages only to never log in after the second week.
One common mistake is ignoring the TOEFL iBT official practice sets in favor of third-party mock exams. I once spent three weeks strictly following a prep book’s mock tests, only to realize on exam day that the actual interface and the logic of the questions were subtly different. It was an unexpected outcome that knocked my confidence during the test. Was it worth the extra stress? I’m still not sure. Sometimes, just doing nothing and resting for a few days to recalibrate is more effective than forcing yourself through another set of poorly designed practice papers.
Choosing a path depends entirely on your current level. If you are starting from a place where you don’t know the format, a classroom or a structured online program helps build the initial framework. However, once you hit that plateau, no lecture will save you. You need to pivot to intense, self-directed drilling. The reality of language testing is that it’s less about the school you choose and more about the specific hours you spend analyzing why you missed a specific nuance in a listening passage.
This advice is useful for working professionals who need to maximize their limited study time without overspending. However, if you are a student who struggles with procrastination or has no concept of how to structure a study routine, self-study might be a disaster for you. A realistic next step is not to buy a new book or sign up for a ‘pass,’ but to take one full-length, official practice test this weekend to identify your baseline without any preparation. Be aware: the online score predictors are often slightly more generous than the actual IBT testing environment, so don’t be shocked if your official score comes back lower than your practice results.

The commute cost really highlights the inefficiency. I found myself wasting so much time traveling to and from lessons, which actually hindered my ability to focus on the material itself.
