Middle School Science Quiz App Review: 3,000 Questions for M.1–M.3 (Grades 7–9) with Full Explanations
Middle school science builds on itself year after year. A shaky foundation in Grade 7 tends to show up as frustration in Grades 8 and 9. One of the most reliable ways to stay on top of it is a good middle school science quiz app that lets students practice regularly and actually understand why each answer is right.
In this review, ChatStick looks at its newly released app, “ตะลุยโจทย์วิทย์ ม.1-3 3000ข้อ” (Science Practice M.1–M.3, 3,000 Questions). It packs 3,000 science questions into a single app that students can use from M.1 (Grade 7) all the way to M.3 (Grade 9), guided by Niew, a little otter scientist mascot. It runs on iPhone, iPad and Apple silicon Macs.
Who This App Is For
The question bank follows Thailand's Basic Education Core Curriculum B.E. 2551 (revised B.E. 2560), Science and Technology strand, and the App Store description is written in Thai. That makes it a natural fit for students in Thai schools, Thai-program students at international schools, and parents or tutors supporting them. If you are preparing for midterms, finals or the M.4 entrance exams, the three-year structure lets you revisit earlier grades whenever a topic feels weak.
What's Inside: 3,000 Questions Across Three Years
Level | Stage name | Questions |
M.1 (Grade 7) | Explore | 1,000 |
M.2 (Grade 8) | Experiment | 1,000 |
M.3 (Grade 9) | Master | 1,000 |
Questions cover biology, chemistry, physics, and earth and space science. Each one is tagged with one of four levels (remember, understand, apply and challenge), and many include built-in science illustrations so students can see the concept, not just read about it.
