Grade 10 Biology Practice App Review: 1,000 Questions Across 7 Chapters
Grade 10 biology covers a lot of ground: facts to memorize, processes to understand, and genetics calculations that trip up many students. Re-reading notes only gets you so far. What actually moves your score is working through grade 10 biology practice questions regularly and understanding why each answer is right and why the others are wrong.
In this review, ChatStick looks at its newest study app, “ตะลุยโจทย์ ชีววิทยา ม.4” (Biology Practice for Grade 10 / Mathayom 4). It packs 1,000 questions built on the Thai IPST (สสวท.) additional biology curriculum, so students can read a summary, practice, learn the reasoning and review weak spots in one app on iPhone and iPad. The question content is written in Thai, making it ideal for students in the Thai school system.
Why Grade 10 Biology Needs Plenty of Practice
Grade 10 lays the foundation for all of upper-secondary biology: the chemistry of life, cells, DNA, genetics and evolution. Gaps here make every later chapter harder. Practicing many question types shows you how the same concept can be tested in different ways, from interpreting diagrams and experimental data to working out Punnett squares, so you walk into midterms, finals and later A-Level biology with more confidence.
Meet the App: Biology Practice for Grade 10 by ChatStick
The app is built specifically for Grade 10 science-track students. Its mascot, Bio, a little snake biologist in glasses, acts as a study buddy and cheers you on as you work. The two standout strengths are explanations that teach the reasoning rather than just revealing the answer, and a review system that automatically picks the questions you should revisit.
1,000 Questions Across All 7 Chapters
Chapter 1, The Study of Biology: characteristics of life, scientific inquiry, variables, data analysis
Chapter 2, Chemistry of Life: water, carbohydrates, proteins, lipids, nucleic acids, enzymes
Chapter 3, Cells and Cell Function: microscopes, organelles, membrane transport, cellular respiration, cell division
Chapter 4, Chromosomes and Genetic Material: DNA structure, replication, transcription, translation, mutation
Chapter 5, Inheritance: Mendel's laws, Punnett squares, blood groups, sex-linked genes, pedigrees
Chapter 6, DNA Technology: recombinant DNA, PCR, gel electrophoresis, GMOs, bioethics
Chapter 7, Evolution: evidence of evolution, Lamarck and Darwin, Hardy–Weinberg, speciation
Question formats include multiple choice, diagram analysis, experimental data analysis, genetics calculations, sequencing, matching and statement analysis, organized into four levels: Basic, Standard, Exam-style and Challenge. You can build from the fundamentals up to the toughest items.
Key Features That Build Real Understanding

Hints: nudges your thinking without giving the answer away
Mistake notebook and Smart Review: wrong answers are saved automatically, and Smart Review picks “10 questions to review today” based on your accuracy and repeated mistakes
Daily Challenge: 10 mixed-chapter questions a day to build a steady habit
Mock exams: Mini Test (20), Standard (40) and Full (60 questions), with an optional timer and per-chapter weakness analysis
Custom Practice and Bookmarks: choose chapter, topic, level and question type, save questions, and track progress by chapter
Core features work offline: with Dark Mode and adjustable text size
How to Use the App to Prepare for Midterms and Finals
Read the lesson summary for the chapters on your exam and note any key terms or comparison tables you find confusing.
Use Custom Practice to focus on those chapters, starting at Basic and moving up to Standard and Exam-style.
Read every explanation, even for questions you got right, to confirm you understood rather than guessed.
Open Smart Review daily and clear the 10 suggested questions until your mistake notebook shrinks.
A week before the exam, take a timed mock test and use the analysis to see which chapters still need work.
Tip: For genetics problems, draw the Punnett square yourself first, then compare it with the STEP 1–4 solution. You will remember the method far better than by reading alone.
