The Journey

The steps before going to the international stage.

01
First Stage
(Foundation)
You need to finish your class science book. Try to understand the material rather than just reading through it. Cultivate the habit of asking "Why?" and "How?"
🎓
02
Second Stage
(Advanced)
It is crucial to learn the textbooks for the next grade, solutions to mathematical problems, geometry, logic, and the foundations of scientific thinking.
03
Third Stage
(Reference)
Reading selected chapters from international reference books such as 'Campbell Biology' or 'University Physics'.
📖
04
Fourth Stage
(Verification)
Identifying and rectifying one's weaknesses by solving questions from previous years.

Subjects to Read

Capturing moments of discovery, competition, and celebration across the nation

Physic

1. Physic 1st Part

This book is primarily written for students in grades 9 and 10; therefore, if you wish, you can read this book before studying the standard board textbooks for these grades. You should read the entire book and also attempt to solve the problems provided at the end of each chapter.

2. University Physics With Modern Physics (14th Edition)

You might feel intimidated at first glance, as the book is written for a university level. However, it is written in very simple language; if you have thoroughly covered the Class 9–10 textbooks, reading this book won't be difficult. The chapters to study are: 1–8, 11 (excluding Torque), 12 (excluding Bernoulli), 13, 14 (excluding Physical pendulum), 17–19, 21, 23, 25, 26, 27 (only the right-hand rule), and 34.

⚗️

Chemistry

1. General Chemistry

The book is written in a very accessible style and is divided into five parts. Reading just the first four parts (Parts 1–4) is sufficient. If you have started gaining confidence by studying your own textbooks, you can use this book to further solidify your understanding of the concepts.

2. Chemistry

There is no better book to start with if you want to dive deep into chemistry. It is written in simple English, and the end-of-chapter problems are excellent. Chapters worth focusing on: 1–6, 8, 9, 11–16, 19, and 23.

Although these two books are used at the university level, the fundamental concepts of chemistry are explained very clearly in them. How deeply you delve into the material depends on the time you have available—studying in alignment with the core IJSO syllabus is the most effective approach.

🧬

Biology

1. Higher Secondary Zoology

2. Higher Secondary Botany

3. Campbell Biology

It is sufficient for comprehensive preparation in the biology section. It features a progression from basic concepts to detailed explanations, all presented in simple language with excellent illustrations. The sections on scientific skills and problem-solving exercises will prove useful for the experimental component of the IJSO.

4. Biology

Thoroughly studying this book alongside the Secondary and Higher Secondary textbooks and *Campbell Biology* will complete your preparation for the biology section.

Marking & Timing

Evaluation Method

  • There will be 12-20 questions in total.
  • The National phase will follow the IJSO format with integrated questions from Physics, Chemistry, and Biology.
  • Primary category questions will be based on the Primary Science textbook.
  • Question papers will be provided in both Bangla and English. Students can answer in their language of choice.
  • Marking for each question may vary.
  • Negative marking may be applicable for incorrect answers in the Regional phase.

Time Limit

The total exam duration is 1.5 hours (90 minutes). All questions must be answered within the allotted time.

The Olympiad will be held in 2 phases: 1. Regional Olympiads nationwide 2.National Finals held in Dhaka

💡 Pro Tips: The beauty of problem Solving

The effort is more important than the solution!

"Remember, simply finding a quick solution isn't everything. The effort put into finding a solution is more important than the solution itself. If someone tries to solve a problem day after day, their brain begins to function even more brilliantly!"

Don't give up; stick with it. One day, you might experience incredible joy!
