What is calorimetry?

Hi.

It's still possible to score 50+ in Physics and Chemistry in your 12th Maharashtra board exams even if your chapters aren't fully completed. The key is strategic preparation and selective focus. Here's a detailed plan:

Step 1: Identify the High-Yield Chapters

Focus on chapters and topics that frequently appear in past papers. In Maharashtra Board 12th:

Physics High-Yield Topics

Electrostatics & Current Electricity

Magnetic Effects of Current & Magnetism

Optics (Ray Optics and Wave Optics basics)

Modern Physics (Photoelectric effect, Nuclear Physics)

Mechanics (Simple concepts, Work Energy Power, Laws of Motion)

Chemistry High-Yield Topics

Coordination Compounds (very scoring)

Surface Chemistry

Electrochemistry

Organic Reactions (Alcohols, Aldehydes, Ketones, Carboxylic acids)

Chemical Kinetics and Equilibrium

Step 2: Use Short Notes & Formulas

Make a one-page formula sheet for physics and chemistry reactions/equations.

Focus on derivations or reactions that are directly asked. Don't spend time on long, rarely asked derivations.

Physics: Formulas for mechanics, optics, electrostatics, magnetism, modern physics.
Chemistry: Reactions, order of reactivity, p-block, d-block essentials, and common organic reaction mechanisms.

Step 3: Solve Previous Years' Board Papers

Pick last 5–10 years' questions. Maharashtra board often repeats questions with slight variations.

Solve at least 1 full paper per subject in exam conditions.

After that, focus on repeated or frequently asked questions.

Step 4: Do Selective Practice

Don't aim to finish the entire syllabus now — instead:

Physics: Solve numericals from previous exams, especially simple formula-based questions.

Chemistry: Memorize reactions and practice writing them cleanly; inorganics can be learned quickly with tables.

Step 5: Time Management

Allocate 2–3 hours per day for Physics and 2–3 hours for Chemistry.

Divide each day: 50% theory revision + 50% numericals/practice.

Step 6: Smart Exam Strategy

Attempt easier chapters first in the exam.

Write formulas and reaction equations clearly — even if you skip some parts, correct formulas fetch marks.

Don't waste time on very hard questions — move to the next.

Step 7: Quick Revision Tools

Crash course notes or NCERT summary PDFs.

Estimated Marks Strategy

If you target high-yield chapters + repeated questions:

Physics: 25–30 marks from numericals + 20 marks theory → 50+

Chemistry: 25–30 marks from inorganics/organic reactions + 20 marks theory → 50+
