- Periodic classification
- Solid state, and
- Properties of metals and nonmetals.
Instrumentation Chemistry
The branch of Chemistry that focuses on qualitative and quantitative analysis of substances using classical and instrumental methods is covered under Instrumental Chemistry. Some of the important techniques that are useful for practical applications in this field are as follows:
- Spectroscopy,
- Chromatography and
- Electrochemistry
General Aptitude
The General Aptitude paper covers verbal and numerical skills and analytical thinking in the GATE exam, which is common for all GATE papers. It contributes a significant weightage to the exam. This section can be a plus point for those who have a strong grasp of accuracy and speed. The subtopics of General Aptitude include:
- English Comprehension & Grammar
- Basic Maths
- Data Interpretation
Note: With daily practice of English comprehension, basic mathematics, and data interpretation questions, you can score full marks and keep yourself ahead of other students in the GATE 2026 Chemistry exam.
Engineering Mathematics
Engineering Mathematics is a field of applied mathematics that deals with mathematical models and techniques.
These topics are helpful in modeling and problem-solving applications in biotechnology. Engineering Mathematics can be considered a high-scoring Chemistry topic for the GATE 2026 exam.

Common Mistakes to Avoid While Preparing High-Scoring Chemistry Topics
Most of the students preparing for the GATE Chemistry exam often make some common mistakes that can affect their overall performance in the exam. Some students ignore PYQ, which is considered one of the best sources of preparation. The following are common mistakes to avoid while preparing high-scoring topics mentioned below in tabular format:
|
Mistake |
Problem |
Solution |
|
Overlooking NCERT Textbooks |
NCERT books are an important resource for the preparation of any competitive exam. |
|
|
Focusing only on theory and skipping numerical problems |
Poor problem-solving speed and inability to apply theories in GATE-type questions |
|
|
Learning reactions without understanding the latest trends in inorganic and organic Chemistry |
Difficulty in recalling and applying the correct periodic trends during the exam |
Try to understand the logic and concepts behind periodic trends (atomic size, electronegativity, etc.) before learning |
|
Neglecting MSQ& NAT question formats |
Although MSQ & NAT are in long-question format but these are mainly based on concepts. |
Try attempting MCQ and NAT format questions to increase your score and performance. |
Conclusion
Smart and disciplined study can help you crack the GATE Chemistry 2026 exam. For this, you need to follow a strict routine with a regular process of attempting mocks/PYQs.
