Chemistry often trips students up because it isn't really one subject — it's three (organic, inorganic, and physical chemistry) that reward different study approaches, taught under one label. Treating all of Chemistry with the same study method is a common reason students plateau.
Organic Chemistry: Understand Mechanisms, Don't Memorize Reactions
Organic chemistry has a reputation for requiring memorization of hundreds of reactions — but students who understand the underlying mechanisms (how and why electrons move in a reaction) can predict reaction outcomes they've never explicitly seen before, rather than needing to have memorized every specific case. Focus study time on understanding electron movement, functional group behavior, and common mechanism types (substitution, addition, elimination) rather than rote-memorizing a long list of named reactions in isolation.
Inorganic Chemistry: Patterns Across the Periodic Table
Inorganic chemistry rewards recognizing periodic trends — how reactivity, atomic size, and bonding behavior change across periods and groups — rather than memorizing the properties of each element individually. Once the underlying trend is understood, predicting the behavior of an unfamiliar element or compound becomes far easier than trying to recall a memorized fact about that specific substance.
Physical Chemistry: This Is Where Math Skills Matter
Physical chemistry (equilibrium, thermodynamics, reaction rates, and related calculations) is the most math-heavy part of the subject. Students strong in Math but weaker in Chemistry often do best here, while students who are comfortable with organic/inorganic content sometimes struggle with the numerical demands of physical chemistry. Treat it with the same timed problem-solving practice you'd use for Physics or Math.
A Practical Study Approach
- Separate your revision time explicitly into organic, inorganic, and physical chemistry rather than treating "Chemistry" as one undifferentiated block.
- For organic chemistry, practice drawing out mechanisms by hand rather than only reading about them.
- For inorganic chemistry, build comparison tables of periodic trends rather than memorizing isolated facts.
- For physical chemistry, do timed calculation practice the same way you would for Math or Physics.
- Use past papers across all three areas to identify which specific type is your actual weak point — a generic "I'm bad at Chemistry" self-assessment usually hides a more specific, fixable gap.
Common Questions
Is Chemistry harder for MDCAT than O Level/A Level? The content builds on the same fundamentals, but MDCAT demands much faster MCQ-based recall and problem-solving under time pressure, so exam-style timed practice becomes more important as the test approaches.
Why can I understand a Chemistry topic in class but not solve exam questions? This is common when a topic was learned passively — actively solving a wide range of problems on that topic (not just reviewing notes) closes this gap.
Should I focus more on organic or inorganic chemistry? This depends on your specific syllabus's weighting — check your board's or test's exact breakdown rather than assuming equal weighting.
Our Chemistry tutors work with students separately on organic, inorganic, and physical chemistry depending on where the actual gap is — see our Find a Tutor page, or the Test Preparation Hub for MDCAT-specific Chemistry strategy.
