Applying to an overseas MBA program is a major turning point in the career of many Japanese business professionals. However, aspiration alone is not enough; you need to prepare to meet the requirements of the admissions review. Especially important are **TOEFL and IELTS, which prove your English ability**, and **the GMAT, which measures logical thinking and quantitative analysis skills**.
These tests are not mere formalities; they demonstrate the foundational academic ability needed to study in an MBA program, take part in discussions, and work through case studies. Your scores are therefore directly tied to the admissions decision.
This article organizes the characteristics of and strategies for TOEFL, IELTS, and GMAT, which are needed to apply to an overseas MBA, and introduces the steps for efficient preparation. Use it as a guideline for studying strategically if you are aiming to study abroad.
In MBA applications, submitting a score from either TOEFL or IELTS is required in most cases. In general, **US business schools tend to prefer TOEFL**, while **IELTS is widely accepted at business schools in the UK, Australia, and Asia**. However, many schools now accept both, so it is practical to choose according to your own strengths.
The GMAT (Graduate Management Admission Test) is a standardized test for measuring the logical thinking and analytical skills of MBA applicants. Many top schools require it, and it comprehensively assesses not only English ability but also **quantitative reasoning, logical reasoning, and reading comprehension**.
The test consists of the following four sections:
For MBA application preparation, **a planned effort of more than a year** is the key to success, rather than a short intensive push. Especially if you are preparing while working, designing a schedule with room to spare is essential.
The tests required for overseas MBA applications cover a wide range and are hard to conquer in a short time. To make the most of your limited time, it is important to choose study methods strategically.
TOEFL, IELTS, and the GMAT are the first big hurdle for MBA applicants.
By keeping these three points in mind, even busy working adults can aim for a passing score. Preparing early is the shortest route to admission.
What scores are generally needed to apply to an overseas MBA?
As a general guide, top schools expect TOEFL iBT 100 or higher or IELTS 7.0 or higher, and GMAT 700 or higher. For upper to mid-ranked schools, TOEFL 90 / IELTS 6.5 and a GMAT around 650 serve as one benchmark (be sure to check each school's published figures).
Should I take TOEFL or IELTS?
If the schools you plan to apply to accept both, choose based on your aptitude. If you are strong at academic reading and integrated writing, TOEFL suits you; if you are strong at face-to-face speaking and listening to varied accents, IELTS suits you.
Is it better to study for the English test and the GMAT in parallel or in sequence?
In principle, we recommend doing them in sequence. Locking in the required score on the English test first and then concentrating on the GMAT is advantageous for study efficiency and mental management.
When is the ideal time to start studying?
Ideally, 18 months before applying. Spend the first 3-6 months on TOEFL/IELTS, then 6-9 months on the GMAT, and use the remaining 3 months to prepare essays, recommendation letters, and interviews.
What is the priority order for GMAT section-by-section preparation?
Quant: train to solve frequently tested patterns (algebra, ratios, sets, probability) quickly / Verbal: stabilize accuracy in CR and SC first, then read RC by structure / IR/AWA: get used to the format with templates + official questions
How many times should I go through the official question books and mock tests?
For every test, going through the official question books repeatedly is a must. Take mock tests about once a month (every other week near the test date) under the same conditions as the real test, and devote at least 50% of your study time to review.
What is the remedy when my score plateaus?
Visualize weaknesses (quantify accuracy by question type and skill) / identify causes (vocabulary shortage, sentence processing, calculation errors, time allocation) / make a countermeasure list (10-20 minutes of daily weak-point drills, measure the effect weekly)
What are tips for securing study time as a busy working adult?
Weekdays: 90 minutes of morning study + 30 minutes of commute input / Weekends: two sessions of 3-4 hours of consolidated practice / Build the habit by cutting off your smartphone and using study triggers (same time, same place, same background music)
How should I train English speaking?
For IELTS prep, do mock interview sessions 2-3 times a week; for TOEFL, make a routine of recording 60-90 second answers using question templates, self-scoring them, and practicing rephrasing.
What is an effective way to practice writing?
Fix a structure template (introduction -> claim -> two supporting points -> rebuttal handling -> conclusion), and raise accuracy in this order: timed practice -> compare with model answers -> grow your stock of expressions.
I am weak at listening. In what order should I improve?
Correct sound recognition with dictation / automate sound perception with shadowing / optimize for the test format with key-point notes + previewing the questions
How do I build vocabulary?
Manage a list of frequent academic vocabulary with SRS (spaced repetition), and make a habit of encountering words in reading -> making example sentences -> recalling them five times. Learning by part of speech and collocation makes the words easier to apply.
What about score validity periods and retake strategy?
At many schools, scores are valid for about 2 years. To avoid leaving uncertainty right before applying, lock in the English test early, and plan the GMAT with a buffer (an extra 1-2 attempts).
If I can't reach the target score, can other strengths make up for it?
If you have reached a certain level, you can compensate with your work record, leadership, essays, recommendation letters, and interview. However, falling below the minimum requirement may mean your application is not accepted at all, so clearing the lower limit comes first.
Should I use a school or coaching?
It is effective if you are stuck when studying alone. You get an objective diagnosis of weaknesses, correction of your answers, and optimized time allocation. Evaluate cost-effectiveness by “the amount your recent score has improved.”
How does this relate to application documents (essays and recommendation letters)?
If your test scores are locked in early, you can devote enough time to essay strategy (career consistency, post-MBA goals, fit with the school). As a guide, ask your recommenders 6 months before applying.
How should I spend the final stretch?
Rehearse the start time, breaks, and nutrition exactly as on test day with same-condition mock tests / Don't touch new materials; go over your notebook for preventing repeated mistakes / Fix your sleep schedule (match your bedtime and wake-up time to test-day times for 7 days in a row)
How do I recover if my study plan falls apart?
Narrow your weekly “to-do” to three items and carry out the most important task first. Do not slide unfinished items to the next week; discard them and redesign the plan. Prioritize continuity over perfectionism.
Final Checklist
Check the test format, what to bring, and ID documents / Register score recipients (school codes) in advance / Plan test-day travel, venue route, and a backup plan / Memorize the real test tempo (time allocation for each section)
