A-Level Biology Practice 1000 Review: 1,000 Questions, Full Solutions and Timed Mock Exams
Thailand's A-Level Biology exam covers a huge amount of ground, from cells and the human body to plants, genetics and evolution. Reading summaries alone rarely moves the score. What does is steady A-Level Biology practice questions with explanations that show why each answer is right.
In this review we look at A-Level Biology Practice 1000 (ตะลุยโจทย์ ชีวะ A-Level 1000), a new app from ChatStick that went live on the App Store on 12 October 2026. It packs 1,000 newly written biology questions, step-by-step solutions, timed mock exams and a smart review system into one app for iPhone and iPad. Note that the question content is written in Thai, for students preparing for Thai university admissions.
Why question practice matters for A-Level Biology
The A-Level Biology paper tests more than memory. Students must read graphs, tables and experimental results, and judge several statements within a single item. If you meet these formats for the first time in the exam room, you lose valuable minutes. Regular practice with exam-style questions helps you recognise patterns, find your weak topics and manage your time.
Meet A-Level Biology Practice 1000
Developed by ChatStick Company Limited, the app focuses only on A-Level Biology. A study companion, Axie the Axolotl, cheers you on each day and helps point out weak areas. Every question is stored on the device, so you can practise without an internet connection.
Five categories, 27 chapters, three difficulty levels
The 1,000 questions are organised into 5 main categories and 27 chapters, with three difficulty levels: foundation, exam level and challenge.
Category | What you practise |
Biodiversity and Environment | Diversity of living things and ecosystems |
Basic Units of Living Things | Cells and cell division |
Human and Animal Body | Body systems such as the heart |
Plant Biology | Plant structure and function |
Genetics and Evolution | Inheritance and evolution |
Question formats that mirror the real exam
Five-option multiple choice: pick the single best answer
Complex items: decide whether each statement is true or false
Data-based items: interpret graphs, tables, experimental results and diagrams of cells, the heart, cell division and genetics, with tap-to-zoom images
Detailed solutions for every question
The solutions are the core of the app. Each one is broken into six parts:
The correct answer
The key concept
Step-by-step reasoning
Why the other options are wrong
An exam-taking tip
A short summary that is easy to remember
Complex items include a separate explanation for every statement, so you can see exactly where you went wrong.
Ten timed mock exams
Each set has 40 questions, 90 minutes and 100 points
Scoring follows the real exam format: 2.4 points per multiple-choice item, 3.2 points per complex item, or 1.6 points when 2 of 3 statements are correct
New sets are generated from a blueprint and avoid questions you took recently
Results are broken down by category, with weak-area practice one tap away
You can leave mid-exam and resume later
Review and readiness tools
Smart Review: daily suggestions based on repeated mistakes, slow answers and long gaps since your last review
Mistake notebook: records the cause of each error
81 concept cards: illustrated cards for a quick refresh before practice
A-Level readiness check: a planning tool, not a score prediction
Statistics and study plans: accuracy by category, chapter and difficulty, average time per question, and a plan built around your exam date and target score
On iPad: show the question beside the choices, or beside the solution, in split view
Tip: start with foundation questions in your weakest category, then take one mock exam a week to track progress.
