If you Googled "30 day TOEIC study plan" and landed on five different sites all telling you to study three hours a day, close those tabs. You have a job, or classes, or both, and the person who wrote that plan has clearly never had either.

I've spent years teaching English to Indonesian students and watching what actually works. The short version: you don't need three hours a day. You need the right forty-five minutes, six days a week, and a clear sense of which parts of the TOEIC are costing you the most points. This post gives you both.

Quick note on who I am. I'm a teacher at Auravale Academy, we build ESL materials for Indonesian learners, and I've watched hundreds of students go from mid-400s to 700+ in a single month. Not because they're geniuses. Because they stopped wasting study time.

Before you open a single book, do this

Take a timed, full-length TOEIC practice test. Not half of one. A full one. 45 minutes of Listening, 75 minutes of Reading, in one sitting, with your phone in another room.

Yes, it will feel brutal. That's the point. You cannot plan a study schedule without knowing where you actually are. A lot of people skip this step because it feels discouraging. Skipping it is how you end up studying the wrong things for four weeks.

Write down your raw score for each of the seven parts. The one where you got the fewest correct is where most of your next month goes. Everyone's weak spot is different. Some Indonesian students crush Listening and fall apart on Part 7 Reading. Others breeze through Reading and can't follow the audio at natural speed. Until you know which one is you, every "tip" on the internet is a guess.

The 30-day plan, broken into four weeks

Each week has a theme. Each day is 45 minutes of focused work, six days a week. One rest day. Rest is part of the plan, not a break from it.

Week 1: Diagnose and rebuild the foundation (Days 1 to 7)

Day 1: Full practice test. Score it. Write down your weakest section.

Days 2 to 6: 45 minutes per day, split like this:

  • 15 minutes: vocabulary. Specifically, business and office English. Meetings, emails, schedules, invoices, hiring, travel, logistics. Skip the generic "1000 English words" lists. Those words aren't what TOEIC tests.
  • 15 minutes: grammar for Part 5. Focus on the three structures that show up over and over: verb tenses, word forms (noun vs adjective vs adverb), and prepositions.
  • 15 minutes: listening practice. Not music, not Netflix. Business podcasts, office phone calls, short news clips. Play them at normal speed even when it hurts.

Day 7: Rest. Completely. No English. Your brain consolidates what you learned while you're not studying.

Week 2: Attack your weakest section (Days 8 to 14)

This is where most generic plans fall apart. They give everyone the same week 2. You need the opposite. If Listening is your problem, spend most of this week on Parts 1 to 4. If Reading is the problem, it's Parts 5 to 7.

For Listening-weak students:

  • Part 2 (Question-Response) gives the fastest score improvement. Do 30 questions a day for six days, and listen for the first word of the question. Who, what, when, where, why. That one habit alone usually gains 20 to 40 points.
  • Part 3 and 4: read the questions before the audio plays. Always. This is the difference between passive listening and active listening.

For Reading-weak students:

  • Part 5 is 30 grammar questions in a section where time pressure is real. Practice answering each one in 20 seconds or less. If you can't, move on.
  • Part 7 eats time. The trick is reading the questions first, then scanning the passage for the answers. Most Indonesian students read top to bottom like it's school. TOEIC isn't school. It's a time test disguised as an English test.

Day 14: Another timed mini-test, just the sections you worked on. Compare to Day 1. Celebrate the gain, however small.

Week 3: Build stamina (Days 15 to 21)

Most people who run out of time on the real test didn't run out of English. They ran out of focus. Two straight hours of testing is a physical skill.

This week, do one full timed half-test every other day (Listening only, or Reading only), plus 30 minutes of vocabulary and targeted weakness work on the other days. By the end of week 3 you should be comfortable sitting for 75 minutes of Reading without your eyes blurring.

If your focus collapses at the 30-minute mark, that's not a language problem. That's a training problem, and training is what week 3 is for.

Week 4: Simulate, refine, rest (Days 22 to 30)

Day 22: Full timed practice test. Exactly like test day. Morning if possible, since that's when most real TOEIC sessions are scheduled.

Days 23 to 27: Review the test question by question. Not "I got it wrong, moving on." Actually understand why you got it wrong. Was it vocabulary? Grammar? Time pressure? A distractor word that sounded like the right answer? Each mistake is data. Fix one small category per day.

Day 28: Second full timed practice test. Look for patterns. Most students see a jump of 50 to 150 points from Day 1 to Day 28 if they did the work honestly.

Day 29: Light review. Vocabulary flashcards, a few Part 2 questions for warmth. Nothing heavy.

Day 30: Rest completely. Sleep early. Eat a normal breakfast on test day. Do not try to learn anything new in the final 24 hours. It doesn't stick, and it makes you nervous.

The three mistakes I see Indonesian students make every month

Studying vocabulary without context. Memorizing a list of 500 words and their Indonesian translations is almost useless for TOEIC. The test asks you to choose the right word for a specific office scenario. You need to see words inside business emails, not in a flashcard app by themselves.

Ignoring Listening until the last week. The Indonesian school system trains students to read English far better than they hear it. On TOEIC, Listening is half your score. Start early and keep going.

Treating every question equally. A 20-second Part 5 question and a two-minute Part 7 question are worth the same point. If you spend four minutes on one hard Part 7, you just lost the chance to answer three easier questions elsewhere. Learn to skip. The students who finish the Reading section almost always beat the students who don't, even if they guess on the skipped ones.

What about apps and courses?

Honest answer: most of them are fine. A few are excellent. None of them matter if you don't put in the 45 minutes a day. The plan above works with a single TOEIC practice book, a notebook, and headphones. If you want to add a course later, add it. But don't wait for the perfect tool before you start.

One last thing

Your score on Day 1 is not who you are. It's a starting line. I've watched students who scored 380 on their first attempt walk out of the real test a month later with a 650. They didn't work more hours than everyone else. They worked on the right things.

Start tomorrow. Take the first practice test. Everything else follows from there.
