IB Chemistry Overview

The International Baccalaureate (IB) Chemistry syllabus is designed to provide a comprehensive understanding of its fundamental principles and concepts. It is a two-year course of study typically taken by students in their final two years of high school. IB Chemistry is a prerequisite for several other tertiary courses, such as medicine, environmental science and biological science.

The syllabus emphasises on the importance of practical work, including experimental design, data analysis, and the communication of scientific findings. Students are expected to complete a minimum of 60 hours of practical work during the course. This includes a range of experimental investigations and practical activities.

Assessment on the IB Chemistry course is based on a combination of internal and external assessments. Internal assessments include practical work and individual investigations, while external assessments include written exams and an independent research project. The course aims to prepare students for further study in chemistry at the university level and to develop their critical thinking, problem-solving, and experimental skills.

The IB Chemistry course is divided into four main areas:

Stoichiometric Relationships

This area covers the quantitative relationships in chemical reactions, including the mole concept, chemical equations, and calculations involving concentration, gas laws, and energetics.

Atomic Structure

This area covers the structure of atoms, the periodic table, and chemical bonding. It also covers the properties of matter and the behaviour of gases.

Periodicity & Properties of Elements

This area covers the properties of elements, including their reactivity, acidity, and basicity. It also covers the chemistry of groups of elements, such as the alkali metals, the halogens, and the transition metals.

Chemical Kinetics, Equilibria, & Organic Chemistry

This area covers the rates of chemical reactions, chemical equilibrium, acid-base chemistry, and organic chemistry.

Our Success Stories

My daughter was stuck with her TOK draft and had no idea how to proceed. I checked with a number of tuition centers for help with TOK, but Prep Zone was the one who could get me a tutor at short notice. Her trainer Jessica was highly experienced and guided my daughter through her draft, essay, and presentation.

Mrs. OngParent

I have been a loyal client at PrepZone since my eldest went there for UCAT tutoring. In all, they have helped my 3 kids with UCAT, BMAT, SAT, ACT, IGCSE and IB. Not to mention the last-minute MMI interview preparation that we needed for med school which was fabulous and so well-organized! Do yourself a favor and get one of their big individual packages and ask them to split the hours between your kids – you can enjoy the lowest per-hour rate that way.

Mrs. NgParent

My son used to go to another tuition center but I soon realized he was spending more time with his friends there than studying. I initially was worried about the lack of group tutoring at PrepZone, but soon realized the 1-1 tutoring is more effective. The feedback that the teachers sent to me after each session was very helpful so I could keep track of his progress and motivate him at home.


Prep Zone really helped my daughter improve on her scores for IB Math and English Lang Lit. We started preparation early in Grade 11, and Prep Zone supported us all the way till the final IB exams. The tutors were really nice and helpful, and were also available to help my daughter after office hours if required. The feedback after every lesson was really helpful for me as a parent, since it allowed me to stay up to date as well on my daughter’s progress. She enjoyed the lessons very much, and their online lessons via Zoom were conducted very smoothly. I would really recommend Prep Zone to all students & parents!


I have been a student at Prep Zone since 2018, and they have helped me with my IGCSE exams and then my IB exams. Some of the explanations by the teachers here were better than my school teachers!


My elder daughter joined Prep Zone for SAT tutoring, and we decided to have a trial class for IB Math. We ended up using our leftover hours for IB, and though the May exams were cancelled due to COVID, I felt my daughter was improving and would have performed well on the exam. My son is now using my daughter’s remaining hours, and he loves his weekly tutoring for Psychology & Biology.

B. H.Parent

I had no personal life in IB year 2 and spent 4 days of the week at Prep Zone for SAT, IB and university applications haha. But now I am off to Columbia and it’s been worth it. Thank you Prep Zone!! And special thanks to Michelle, my English tutor there :))

A. S.Student

Went to Prep Zone for Physics, Psychology and Business lessons and they really helped me improve. Pro tip: check with your friends if they are going to Prep Zone as well after school and share a cab there, you’ll be surprised how many show up there 😉

R. T.Student

The great thing about Prep Zone’s IB course was that I could use the hours from my package for multiple subjects rather than getting new packages for each. This helped me during my mocks since I could come in with my doubts for all my HLs.

M. T.Student

I was initially a bit concerned about the price so went for the smallest package. My son loved his lessons and they were nice enough to allow me to move up to the higher package. A big bonus for me as a parent were their regular feedback emails after every session so I could keep track too.

S. B.Parent

I had an amazing tutor, patient, understanding, and flexible, able to find a simple way to explain the hardest questions. I would just like to say that without his help, I would not have improved as much as I did for my promotional exams. Because of his help, my Chemistry attained a 7 with 80 this time around, and my Math improved a startling 18 marks from 52 to 70. We may meet again next year, but I just wanted to ask that he continue helping students who want to learn, as with his patience and guidance there will surely be improvement.


I would like to sincerely thank my trainer for all his help and guidance during my chemistry internal assessment. I met my chemistry teacher a few days back and he told me that my IA was quite good. I got a 7 in chemistry, and I got a 21/24 for my chemistry internal assessment.
Thanks once again for all the guidance and help for the internal assessment!
I was able to pull up from a low grade IA to a much much better one.


The tutors at Prep Zone helped my son get from a 5 in Chemistry to a 7 on his final exams. We had started off with a few sessions to work on Chemical Bonding, but seeing my son’s progress in class, we moved to regular weekly sessions which really paid off! Highly recommend the IB course!
