MHT-CET common mistakes
MHT-CET · Understand the traps and how to avoid them.
Skipping Class 11 Physics chapters such as Rotational Dynamics, Oscillations, and Gravitation because a coaching timetable labels them low-yield, and revising only Class 12 electrostatics and optics.
MHT-CET gives roughly 20% weightage to the Class 11 syllabus, and Maharashtra Board Class 11 chapters generate a predictable set of direct formula and conceptual questions every year; skipping them caps the achievable score.
What to do instead
Reserve the first week of revision for Class 11 chapters, solve the Maharashtra Board textbook exercises plus the last five years' CET questions from those chapters, and keep a one-page formula sheet per chapter.
Substituting numbers into a remembered formula without converting to SI or applying the Board sign convention, especially in mirror and lens problems and in thermodynamic work.
MHT-CET options often differ only by sign, power of ten, or unit; one unconverted gram or centimetre sends the candidate to a plausible-looking wrong option.
What to do instead
Before calculating, write the formula, list the given values with units, convert everything to SI, and assign signs explicitly using the Maharashtra Board convention; drill 20 sign-convention questions per chapter.
Preparing organic chemistry by memorising isolated reactions instead of multi-step conversion sequences, so a question of the form 'A to B to C, identify C' collapses.
MHT-CET organic items are commonly two- or three-step conversions built from the Board textbook reaction charts; isolated memorisation fails when the intermediate is not named in the stem.
What to do instead
Draw a reaction map for each functional group (alcohol, aldehyde, ketone, carboxylic acid, amine) showing reagents and conditions, then solve three-step conversions from the Board question bank.
Postponing physical-chemistry numericals (mole concept, thermodynamics, equilibrium, electrochemistry) to the final days and revising only theory chapters.
These chapters are formula-dense and high-weightage in MHT-CET; last-day revision leaves no time to build the calculation speed the paper demands.
What to do instead
Solve 15 timed physical-chemistry numericals daily from the start of preparation and keep an error log of repeated calculation slips.
Ignoring inorganic chemistry exception lists and periodic trends (ionisation enthalpy anomalies, p-block oxidation states, colours of transition-metal ions) because they feel like rote learning.
MHT-CET inorganic questions are largely one-line factual recalls; candidates who skip exceptions and trends lose easy marks that separate a good percentile from a great one.
What to do instead
Build a one-page exception sheet per block, revise it weekly, and test yourself with 20 rapid-fire MCQs each time.
Spending five or more minutes on a single Mathematics MCQ in the first pass because the question looks solvable and there is no negative marking.
The PCM paper allows about 1.2 minutes per question; one stuck question costs four or five later easy marks, and the paper is designed to reward selective abandoning.
What to do instead
Apply a 90-second rule: if no clear path appears, mark the question and move on; return to it only after finishing the section.
Treating every Mathematics MCQ as a full-length problem and never substituting the options or testing limiting cases.
MHT-CET options are engineered with traps that option-substitution or dimensional and extreme-value checks expose in seconds; full derivations waste time that other questions need.
What to do instead
Practise option-substitution and extreme-value checks on algebra, calculus, and coordinate-geometry questions, aiming to solve about 30% of MCQs by elimination.
Leaving 10 to 15 Mathematics questions blank out of fear of negative marking carried over from JEE or NEET practice.
MHT-CET has no negative marking, so a blank is a guaranteed zero, while an educated guess after eliminating two options has positive expected value.
What to do instead
Attempt every question; after elimination, mark the best remaining option and move on rather than leaving the response sheet incomplete.
Revising only Class 12 Biology and skipping Class 11 Botany and Zoology topics such as plant morphology, animal kingdom, cell cycle, and biomolecules.
About 20% of Biology questions come from Class 11, and these are mostly direct recall items; skipping them costs 15 to 20 marks.
What to do instead
Schedule Class 11 chapters in the first revision cycle, read the Board textbook diagrams and tables, and solve CET questions from those chapters.
Answering Biology from generic NCERT memory when the question is framed from the Maharashtra State Board textbook's wording, examples, or diagram labels.
MHT-CET Biology follows the Board textbook closely; small differences in examples and terminology turn a confident answer into a wrong one.
What to do instead
Read the Board textbook line by line for Class 12 chapters, underline exact wording and examples, and cross-check with the Board question bank rather than outside material.
