The 10th Public Question Paper 2018 Answer Key Science belongs to the Maharashtra SSC Science and Technology I paper. The board also lists Science and Technology 1 and Science and Technology 2 as SSC science subjects.
A solved version of the March 2018 paper is available on education sites such as Shaalaa and BYJU’S, so students can compare their answers with a checked solution set.

What the 2018 Science Answer Key Covers
The answer key for this paper covers the full range of question types used in the exam. The paper includes fill in the blanks, true or false, correct option questions, short answers, scientific reasons, definitions, diagrams, and long answer questions. That means a proper answer key must give both exact one line answers and full step wise answers where needed.
The solved paper shows common SSC style answers such as 1 calorie = 4.18 joule, Dobereiner’s Triads, decomposition reaction, lichen for litmus, concave mirror for a dentist, and 24 ohms for the resistor question. It also gives longer answers on Newlands’ law of octaves, the right hand thumb rule, resistance, pollution, the human eye, myopia, bleaching powder, the electric motor, and refraction of light.

Question Pattern in the 2018 Paper
The paper starts with Section A and uses simple objective and short answer items before moving to descriptive questions. This structure is clear in the original paper, which asks students to complete statements, choose correct options, and then answer short and long questions.
The first part checks basic memory and concept clarity. For example, students had to remember unit conversion, chemical reaction type, mirror type, the source of litmus, and the resistance formula for parallel resistors. These questions test whether the student knows standard textbook facts and can apply them quickly.
The next part checks explanation skills. In the solved paper, questions include Newlands’ law of octaves, the right hand thumb rule, current calculation from power and voltage, drawing the human eye, defining radius of curvature and focal length, and giving scientific reasons. These are the types of answers where method and accuracy both matter.
Important Science Topics From the Paper
The 2018 paper gives a strong idea of which chapters were important for SSC revision. It touches chemistry, physics, and biology together. Students meet periodic table basics, reactions, acids and bases, electrical resistance, magnetism, optics, pollution, and human physiology in one paper.
Here are the main topic areas that appear in the solved paper.
| Topic area | What students were asked |
|---|---|
| Chemistry basics | Calorie conversion, Dobereiner’s Triads, copper sulphate heating, decomposition reaction, Newlands’ law, redox reaction, bleaching powder |
| Physics basics | Mirror used by dentist, parallel resistance, right hand thumb rule, current from power, resistivity, electric motor, refraction of light |
| Biology and environment | Pollutants, litmus from lichen, human eye, myopia, reddish sun at sunrise, degradable and non degradable pollutants |
This table is useful because it shows that the paper does not depend on one chapter only. It checks broad textbook coverage, which is typical of SSC science papers.

How to Use the Answer Key Correctly
A good answer key is not only for checking right and wrong answers. It should also show the exact wording, key terms, and steps that earn marks. In this paper, some answers are one line facts, while others need explanation, formula use, or a labelled diagram.
Students should first solve the paper without looking at the solution. After that, they should compare each answer with the key and mark three things. First, whether the final answer is correct. Second, whether the important scientific term is written correctly. Third, whether the answer has enough steps for full marks. This method fits the structure of the 2018 paper because the paper uses both objective and descriptive questions.
For example, a short answer like 24 ohms is correct only if the calculation is also understood. A diagram question like the human eye is complete only when the diagram is neat and labelled. A reason based answer is complete only when the key scientific idea is written clearly. The solved paper shows this style again and again.

Marking Focus for SSC Students
The original paper clearly says that diagrams should be well labelled wherever necessary. It also says that all questions are compulsory and answers should be written in sequence. These instructions matter because examiners usually reward organised writing and penalise missing steps or unclear presentation.
Students preparing from this answer key should focus on exact science language. A small spelling mistake in a key term can reduce confidence in the answer, even when the idea is correct. The solved paper gives model answers in a direct format, which helps students learn the expected length and style of response.
The paper also shows that SSC science rewards a mix of memory, logic, and formula use. For example, the current from a 60 W bulb at 220 V is solved using I = P/V, which gives 0.272 A in the solution set. That is the kind of answer where the formula, substitution, and final unit all matter.
Common Mistakes Students Should Avoid
Students often lose marks in science because they write partial answers. In this paper, that can happen in definition questions, reason based questions, and diagram questions. A short word answer may be enough for a fill in the blank, but it is not enough for a long answer or explanation.
Another common mistake is skipping the exact scientific term. For example, the paper expects terms like decomposition reaction, concave mirror, lichen, resistivity, and myopia. These are standard textbook words, and the answer key shows them in clear form.
Students also make errors in formula based questions by writing only the final number. In the solved paper, the resistor question is not only about 24 ohms. It also shows the relation used for parallel resistance. That is the safer way to write science answers in SSC exams.
Revision Use for SSC Science Preparation
The 10th Public Question Paper 2018 Answer Key Science works well as a revision tool because it combines theory, numericals, and diagram based learning in one place. The paper is short, but it covers many core science chapters that stay useful for later SSC practice too.
Students can use the paper in three simple steps. First, solve it under a 2 hour time limit. Second, compare every answer with the solved version. Third, list the chapters where marks were lost and revise those textbook topics again. This method is effective because the paper pattern is clear and the answers in the solution set are already arranged in exam style.
