TOEIC Mock Test App for Android: Estimated Scores and Weakness Analysis in TOEIC Prep
Many TOEIC candidates spend weeks drilling individual questions, then walk into the real test and run out of time or have no idea what score to expect. This article looks at the TOEIC mock test app features inside ChatStick's TOEIC Prep for Android: full-length practice exams, estimated scores and weakness analysis, and how they can make your preparation more focused.
Why full-length mock exams matter
The TOEIC Listening & Reading test is divided into seven parts. Practicing part by part teaches you the question types, but it does not prepare you for the stamina and pacing of a complete test. Taking a full mock exam at regular intervals shows where you stand and where the remaining study time should go.
The common problem is what happens after the mock exam. Without a breakdown by part, a list of missed questions and some guidance on what to practice next, a score on its own is not very useful. TOEIC Prep is designed to handle all of that in one app.
About TOEIC Prep
TOEIC Prep (listed on Google Play as “TOEIC เตรียมสอบ ฟัง-อ่าน”) is a Listening & Reading practice app built specifically for Thai speakers, with Thai explanations for every question. It runs on Android, sits in the Education category on Google Play, and is an independently developed study aid that is not affiliated with, sponsored by or endorsed by the test administrators.

Key feature: full mock exams with estimated scores
Listening + Reading mock exams: work through both sections in test format, with a navigator to jump between questions
Estimated score from 10 to 990: results are converted with a versioned score conversion table, so you can set a realistic target
Section results and accuracy by part: see at a glance which parts are strong and which are costing you points
Keep in mind that the app states its scores are estimates only and may differ from an official result. They are best used to track your own progress over time.
Weakness analysis based on your practice data
As you practice, the app turns your answer history into a set of insights that help you decide what to do next.
Score trend graphs show whether your estimated score is moving up
Accuracy by part and average time per question reveal where you are slow or inaccurate
Practice streak statistics help you keep a daily habit
Data-driven recommendations suggest what to practice next
A review center collects incorrect answers, time-consuming questions and saved questions for another attempt
Supporting features that make mock exams useful
Mock exams work best on top of solid daily practice. These parts of the app fit together with them:
All 7 parts: Part 1 Photographs, Part 2 Question-Response, Part 3 Conversations, Part 4 Talks, Part 5 Incomplete Sentences, Part 6 Text Completion and Part 7 Reading Comprehension, with 430 original questions and real photos in Part 1
Practice mode and timed mode: practice mode offers instant answers, hints, audio replay and transcripts, while timed mode builds speed
Thai explanations for every question: why the correct answer is right and why the other options are wrong, plus grammar points, key vocabulary and evidence sentences
1,036 business vocabulary words: 14 categories such as office, meetings, finance, HR and travel, each with Thai meaning, example sentence, audio and spaced repetition review
Adjustable audio and offline use: 0.75x, 1.0x or 1.25x playback in practice mode, and questions, vocabulary and mock exams work without an internet connection
How to get the most out of the mock exams
Take one mock exam first to get a baseline estimated score and accuracy for each part.
Pick the part with the lowest accuracy and read its lesson and strategy guide in the app.
Drill that part in practice mode, using the Thai explanations and transcripts to understand each mistake.
Open the review center and redo the questions you missed or answered slowly.
Take the next mock exam and compare your score trend with the previous round.
The built-in exam preparation guide also includes a 4-week training plan and exam day tips, which make it easier to schedule mock exams around your own calendar.
