ICSE Class 10 Physics Paper Pattern and Marking Scheme 2027

The ICSE Class 10 Physics paper pattern for 2027 is an 80-mark written paper of two hours, plus 15 minutes of reading time. Section A has 40 marks and every question is compulsory. Section B has six questions of 10 marks each, and you answer any four. The other 20 marks of the subject come from internal assessment of practical work in school. I took these details from CISCE's ICSE 2027 specimen paper for Physics, Science Paper 1, and its draft marking scheme.

Two hours for 80 marks is a minute and a half a mark. Physics rewards the student who shows each step quickly, and the marking scheme gives a mark to almost every line of working.

TL;DR

• 80 marks, two hours of writing plus 15 minutes of reading.
• Section A, 40 marks, compulsory: Question 1 has 15 one-mark MCQs; Question 2 carries 10 marks and Question 3 carries 15.
• Section B, 40 marks: any four of Questions 4 to 9, 10 marks each, usually split 3, 3 and 4.
• Internal assessment of practical work adds 20 marks.
• CISCE has not released the 2027 timetable yet.

What is the ICSE Class 10 Physics paper pattern for 2027?

The 2027 specimen, paper code 521, is set out like this:

• Question 1, 15 marks: 15 MCQs of one mark each, including an assertion-reason item. You write only the answer.
• Question 2, 10 marks: six fill-in-the-blanks from a bracket (6 marks), a match-the-columns on levers (2 marks) and a sound graph question (2 marks).
• Question 3, 15 marks: six short questions of 2 marks each and one of 3 marks.
• Questions 4 to 9, 10 marks each: pick any four.

CISCE's note on the specimen says the board paper keeps the same format, though questions can come from any part of the syllabus. Each question carries a tag such as Recall, Understanding, Application or Analysis. In the specimen many Section B parts are tagged Application, so numericals matter. Our ICSE Class 10 Physics syllabus post lists the chapters.

Forty compulsory marks in Section A, then four of six 10-mark questions in Section B.

How long is the ICSE Class 10 Physics exam?

Two hours of writing, after 15 minutes of reading time in which you may not write. Maths is three hours, so a student who sets the same pace for both papers runs out of time in Physics. Time your Physics mocks at exactly two hours.

Physics is two hours plus 15 minutes of reading, an hour less than Maths.

How does the marking scheme give marks?

The draft marking scheme that comes with the specimen shows the mark for each step. Three examples show where marks go.

Units in a calorimetry numerical

Question 5(iii) heats 0.12 kg of copper in a flame and drops it into 0.84 kg of water, which warms from 15 °C to 35 °C. The specific heat capacities are given in J g⁻¹ °C⁻¹ (0.4 for copper, 4.2 for water), but the masses are in kg. The scheme converts them to 400 and 4200 J kg⁻¹ °C⁻¹, writes heat lost by copper and heat gained by water, equates them, and gets a flame temperature of 1505 °C. That is four marks, one for each line. The slip to avoid is converting only one value. Use 4200 for water but leave copper at 0.4, and the flame comes out at about 14.7 lakh °C, a figure that should tell you a unit has gone wrong.

Arrows in a ray diagram

Question 5(i) asks for the image formed by a concave lens. The scheme gives one mark for each of the two rays and one for the virtual, diminished image with arrows. A neat diagram with no arrowheads on the rays loses a mark that took two seconds to earn.

A short numerical with a meter reading

Question 3(ii) shows two kWh meter readings, 856 and 1567, for a 2000 W air conditioner. Energy used is 711 kWh, and 711 divided by 2 kW gives 355.5 hours. The step 2000 W = 2 kW is where students slip.

Convert units before you substitute, draw arrows on every ray, and write each step on its own line.

How should you split the two hours?

My split for a student who is steady across chapters:

• Reading time: read all six Section B questions and choose four.
• Section A: about 55 minutes. The 15 MCQs should take 12 to 15 of them.
• Section B: about 14 minutes for each of the four questions, 56 minutes in all.
• Last 9 or 10 minutes: check units, signs and arrows.

Students often lose time on Question 3, because seven short parts feel easy. Each is worth only 2 or 3 marks, so keep each to about three minutes.

About 55 minutes on Section A, 56 on Section B and the rest to check.

How do you choose four questions in Section B?

1. Read all six in the reading time and mark each as sure, likely or avoid.
2. Check the 4-mark part of each question, not just the first part. It usually holds the longest numerical.
3. Prefer questions from chapters where you have practised numericals by hand: lenses, calorimetry, electricity, levers.
4. Start with your strongest question and write the question number clearly.

Choose during the reading time, and judge each question by its hardest part.

Which mistakes cost the most marks?

• Mixing units in one formula, such as a specific heat in J per gram with a mass in kg, or W with kW.
• Ray diagrams without arrows, or with the image not labelled as real or virtual.
• A True or False answered with no reason when the question asks you to justify.
• Answering five questions in Section B. Only four are required, and the extra one eats about 14 minutes.

Past papers are the best practice for this pattern. Our ICSE Class 10 Physics past papers page has earlier years with solutions, and the ICSE Class 10 Maths pattern post covers the other paper students often find long.
