Why NCERT Solutions for Class 10 Science Are Important
NCERT Solutions for Class 10 Science are important because NCERT is the core source for CBSE board exam paper setting. Science marks depend on concept clarity, correct keywords, and proper explanation. When you solve NCERT questions using structured answers, you learn how to write definitions, give reasons, and explain processes in the exact format expected in board exams.
Science also includes diagrams, flowcharts, and numericals. Many students lose marks by drawing incomplete diagrams, writing wrong labels, or missing units in numerical answers. These solutions help you practice correct presentation and avoid common errors. You also develop confidence for competency-based questions by strengthening fundamentals chapter-wise.
If your goal is to score 90+ in Science, follow this order: complete NCERT textbook questions first, revise important diagrams and definitions, then practice sample papers. NCERT-based preparation also supports foundation-building for competitive exams and higher classes.

Use a fixed method: write given values with units, select the correct formula, substitute carefully, compute accurately, and write the final answer with unit. For Light chapter, practice mirror/lens formula and magnification. For Electricity, master Ohm’s law, series-parallel resistance, and power formulas. Regular timed practice reduces calculation mistakes.
Yes, NCERT Science can be enough for 90+ if you prepare smartly: complete all NCERT questions, revise keywords and definitions, practice diagrams, and solve numericals from optics and electricity. To improve further and handle competency-based questions, practice NCERT Exemplar and 5-10 CBSE sample papers under timed conditions.
Draw diagrams neatly with a sharp pencil, keep lines clean, and label all important parts clearly. Avoid overcomplicated drawings—use NCERT-style standard diagrams. For ray diagrams, draw principal axis properly, mark focus/center clearly, and use correct arrows for incident/reflected/refracted rays. Practice the same diagram multiple times to improve speed and accuracy.

Also practice writing a short, clear practical record with proper headings and conclusions.
Prepare Biology by learning definitions, understanding processes through flowcharts, and practicing NCERT questions. Revise key chapters like Life Processes and Control and Coordination regularly. Maintain a diagram practice list and focus on keywords such as enzymes, diffusion, hormones, reflex action, and heredity terms. Practice short notes for each process to write faster in exams.
Most important formulas are from Physics chapters: mirror formula (1/f = 1/v + 1/u), lens formula (1/f = 1/v − 1/u), magnification, Ohm’s law (V = IR), resistance in series/parallel, and power (P = VI, P = I²R, P = V²/R). Revise these with units and practice numericals to avoid calculation errors.
