After years of teaching Science at Malay Coaching Classes, Indore and reviewing hundreds of student answer sheets, our teachers have identified five mistakes that repeatedly cost students marks. Avoid these and your Science score will improve immediately.
Mistake 1 — Not Drawing Diagrams
Science questions on processes like photosynthesis, refraction of light, the human heart or an electric circuit all expect a diagram. Many students write the explanation but skip the diagram and lose 2 marks per question. A simple, neatly labeled diagram can fetch you marks even if your written explanation is incomplete.
Practice drawing all NCERT diagrams from memory. Label every part clearly. In the exam, draw the diagram first then write the explanation.
Mistake 2 — Memorising Without Understanding
Students who memorise answers without understanding them get confused when the question is rephrased slightly. Science is a subject of concepts. If you understand why something happens, you can answer any variation of that question.
After reading a concept, close the book and explain it to yourself in simple language. If you can explain it simply, you understand it. If you cannot, read it again.
Mistake 3 — Ignoring Chemical Equations
In Chemistry, students often write chemical equations without balancing them and lose marks. An unbalanced equation is considered wrong even if the reactants and products are correct.
Learn all NCERT chemical equations by heart. Practice writing and balancing them daily. 100% accuracy is achievable here with consistent practice.
Mistake 4 — Skipping Numerical Problems in Physics
Many students fear numericals and skip practicing them. Numericals from Electricity, Light and Motion chapters carry 5–8 marks in board exams every year without exception.
Write the formula first, substitute values, show each step clearly. Even if your final answer is wrong, you get step marks for correct method and formula.
Mistake 5 — Writing Very Short Answers for Long Answer Questions
A 5 mark long answer question expects at least 5–6 sentences with relevant points, a diagram and proper structure. Many students write 2–3 lines and wonder why they lost marks.
Look at the marks allocated and write proportionally. For a 5 mark answer, aim for 5 relevant points plus a diagram. For a 3 mark answer, 3 clear points are enough.
Our students at Malay Coaching Classes who correct these habits see an immediate improvement of 10–15 marks in their Science score. Which of these mistakes are you making?
