About the KSEAB II PUC Chemistry Exam
KSEAB II PUC Chemistry covers Class 12 Pre-University chemistry under the Karnataka School Examination and Assessment Board, subject code 34. Content prioritises NCERT Class 12 Chemistry as retained in the rationalized Karnataka PUC syllabus: Solutions, Electrochemistry, Chemical Kinetics, the d- and f-Block Elements, Coordination Compounds, Haloalkanes and Haloarenes, Alcohols Phenols and Ethers, Aldehydes Ketones and Carboxylic Acids, Amines, and Biomolecules. Solid-state and surface-chemistry chapters are often rationalized out — confirm the year's DPUE syllabus. Official assessment is written theory (about 3 h 15 min typical) plus practical, not multiple choice alone. This free English MCQ bank builds concept and calculation fluency before students practise official model papers and practical skills using resources from kseab.karnataka.gov.in, dpue-exam.karnataka.gov.in, and NCERT.
Exam sponsor: Karnataka School Examination and Assessment Board (KSEAB) / Department of Pre-University Education (DPUE). The requirements and fees below concern the certification or admission exam, separate from our free practice resources.
Assessment
Official KSEAB II PUC Chemistry assesses Class 12 Pre-University content through a theory paper lasting about 3 hours 15 minutes (subject code 34), typically with objective-type questions plus short and long answer sections, and a practical / internal assessment conducted separately. Confirm the current model paper and notification for section weights and internal choice. This 100-question bank is an English-language MCQ study adaptation of that written syllabus — it does not fully simulate the official multi-section paper or lab practical format.
Time Limit
Typically about 3 hours 15 minutes for the official II PUC Chemistry theory paper (subject code 34), as commonly scheduled for Karnataka Pre-University science theory papers. Practical exams are scheduled separately.
Passing Score
Pass criteria are as notified by KSEAB/DPUE for the year; Chemistry candidates must satisfy separate theory and practical pass rules as notified. Confirm the current circular rather than unofficial fixed percentages.
Exam / Certification Fees
Included in the II PUC examination fee schedule paid through the college (or as notified for private/repeater candidates). Exact rupee amounts vary by year and candidate category; check the latest fee notification on kseab.karnataka.gov.in / dpue-exam.karnataka.gov.in rather than unofficial fixed quotes.
Exam sponsor websiteFees, eligibility, and exam policies can change. Confirm them with the exam sponsor before applying or paying.
Our practice resources: topics covered
We aim to reflect publicly available exam outlines and topic information in our study resources. Coverage, format, and difficulty may differ from the actual exam, and we cannot guarantee that every detail is accurate or current. Confirm exam requirements, fees, and policies with the official exam sponsor.
Solutions & Colligative Properties
Molarity/molality/mole fraction, Raoult's law, elevation/depression formulas, and osmotic pressure / van't Hoff factor.
Electrochemistry
Cell notation, E°cell, Nernst basics, Kohlrausch ideas, and Faraday electrolysis calculations.
Chemical Kinetics
Rate expressions, order determination, first-order half-life, and temperature dependence of rate.
d/f-Block & Coordination Chemistry
Transition-metal properties, lanthanoid contraction, ligands, IUPAC names, isomerism, and CFT colour/magnetism basics.
Organic Chemistry
Halo compounds through amines: mechanisms, named reactions, and distinguishing chemical tests.
Biomolecules
Sugars, amino acids/proteins, peptide bonds, and reducing vs non-reducing carbohydrate facts.

KSEAB II PUC Chemistry: Suggested Study Strategy
Frequently Asked Questions
Is the official KSEAB II PUC Chemistry exam only multiple choice?
No. Official II PUC Chemistry theory papers (subject code 34) mix objective-type items with short and long constructed-response questions over about 3 hours 15 minutes, plus a practical component. This bank is an English-language MCQ study adaptation for concept and calculation practice only — not a complete official-format simulation.
Does II PUC Chemistry include a practical exam?
Yes. Chemistry is a practical-bearing science subject under Karnataka PUC. Candidates must complete prescribed practical work and appear for theory and practical as scheduled by KSEAB/DPUE for the year.
How long is the Chemistry theory paper?
Theory duration is typically about 3 hours 15 minutes for II PUC Chemistry (subject code 34). Practical exams are scheduled separately. Confirm the model paper and notification for your sitting on kseab.karnataka.gov.in or dpue-exam.karnataka.gov.in.
What is the passing score for II PUC Chemistry?
Pass marks are as notified by KSEAB/DPUE for the sitting, with separate theory and practical requirements for practical-bearing subjects. Always confirm the current year circular rather than unofficial fixed percentages.
What does II PUC Chemistry cost to take?
Chemistry is examined as part of the II PUC examination. Fees are typically paid through the college (or as notified for private/repeater candidates) under KSEAB/DPUE fee schedules. Check official portals for the current schedule.
Which topics should I prioritise?
Cover NCERT Class 12 Chemistry as retained in the rationalized Karnataka PUC list: Solutions, Electrochemistry, Chemical Kinetics, d/f-block, Coordination Compounds, and organic chapters from haloalkanes through biomolecules. Drill molarity, kinetics order/half-life, and cell EMF/Faraday calculations. Use official model papers (code 34) alongside this MCQ bank. Do not assume dropped chapters (e.g., solid state/surface chemistry when rationalized out) are still core unless your year's syllabus lists them.
