Strategies For Tackling Open-Ended Questions In Chemistry

Open-ended questions in Chemistry can be both intriguing and challenging. Unlike multiple-choice questions, open-ended queries require students to think critically, apply their knowledge, and communicate their understanding effectively. As such, mastering the art of tackling open-ended questions is crucial for excelling in Chemistry exams and developing a deeper appreciation for the subject.

In this article, we’ll explore some effective strategies to help you confidently approach and conquer open-ended questions in Chemistry, be it for O Level, IB/IP, or A Level.

1. Understand the question

Before doing anything else, you should fully grasp what the question is asking. Many times, students simply skim through the questions in order to save time, and as a result, they do not craft an answer that the question is asking for or make careless mistakes. This can prevent students from gaining full marks or, in worst-case scenarios, cause students to score no marks at all.

By reading the question carefully, you’ll identify key terms and phrases that provide insight into the specific topic or concept under consideration. Pay attention to any keywords that indicate the type of answer required, such as “explain,” “compare,” “contrast,” or “evaluate.”

2. Organise your thoughts

Before diving into your response, take a moment to organise your thoughts. Consider creating a brief outline or jotting down key points you want to include in your answer. Structuring your response will help you maintain coherence and ensure that you address all relevant aspects of the question.

If you find yourself constantly veering off-topic or providing irrelevant information in your answers, you should implement this technique to avoid such mistakes and identify any gaps or areas that require further elaboration.

3. Draw on relevant concepts

This is a tried-and-tested tip that will allow students to score points. When answering open-ended questions, draw on the relevant Chemistry concepts and theories you have learned in your Chemistry studies. Relate the question to the fundamental principles and apply them to the specific scenario or problem presented. By demonstrating a strong understanding of the underlying concepts, you will impress your examiner by showcasing your knowledge and inference skills.

4. Show your thought process

In open-ended questions, examiners are often interested in understanding your thought process and problem-solving skills. Don’t be afraid to show your work and the steps you took to arrive at your answer. Justifying your reasoning can earn you extra points, which can come in handy if you’re unsure about the final answer or if the answer you’ve derived is not entirely correct.

5. Time management

It goes without saying that open-ended questions can be time-consuming, so it’s crucial to manage your time effectively during exams. Allocate time for each question based on its weightage and complexity. If you find yourself spending too much time on one question, move on and come back to it later if time permits. It will do you no good to spend ample time on just one question.


Tackling open-ended questions in Chemistry requires a combination of knowledge, critical thinking, and effective communication. As long as you practise regularly, manage your time wisely during exams, and seek feedback to continually improve your open-ended response skills, you’ll be well-equipped with the right tools to conquer any open-ended question in your Chemistry exams.
