Why It Is Important to Solve PYQs for JEE Mains & NEET
In JEE Mains and Even in NEET — Questions Repeat.
If someone tells you “questions don’t repeat in JEE or NEET,” show them the data. Because they do. And not just sometimes. It happens often — across Physics, Chemistry, Mathematics, and Biology.
The truth is, these national-level exams are built on a finite syllabus — and exam setters must create thousands of questions every year. In JEE Mains alone, two sessions result in 1800+ new questions annually. Despite best efforts, conceptual repetition is inevitable.
Let’s explore why solving PYQs (Previous Year Questions) should be at the core of your exam strategy.

1. PYQs Reveal Repetition Patterns Backed by Data
Statistical clustering and time series analysis show it clearly: JEE and NEET questions often repeat — if not verbatim, then in concept.
Here’s why:
- The syllabus doesn’t change much.
- The number of unique question formats is limited.
- Similar ideas are asked year after year — just with different numbers or wording.
That’s why solving PYQs boosts both recognition and recall. You’ve seen the pattern before, and your brain activates the right formula, fast.
2. Real Examples: Predicted Questions vs Actual JEE 2025
Predicted Question
A light rope is wound around a hollow cylinder of mass 5 kg and radius 70 cm. The rope is pulled with a force of 52.5 N. The angular acceleration of the cylinder will be ____ rad/s².
Actual Question Jee Mains 2nd April 2025 Shift 1
Find angular velocity when 1 m rope is pulled.

Question 2 |
Similarity? |

Involves hollow cylinder |
✅ Yes |
Involves Circular Disc |

Rope pulling |
✅ Yes |
✅ Yes |

Rotational motion |
✅ Yes (α) |
✅ Yes (ω) |
✅ |
|
Uses force and radius |
✅ F & r given |
✅ Implied through length pulled |
✅ |
|
Final target |
Angular acceleration |
Angular velocity |
❌ Different output |
Conclusion: These questions are conceptually very similar. Both involve applying Newton’s second law for rotation on a hollow cylinder with a rope. One asks for angular acceleration (α), the other for angular velocity (ω), but both use the same system and depend on torque and moment of inertia.
Predicted Question
The magnetic field at the centre of a circular coil of radius r, due to current I flowing through it, is B. The magnetic field at a point along the axis at a distance r/2 from the centre is:
Actual Question Jee Mains 2nd April 2025 Shift 1
The ratio of magnetic field at the center of a circular coil to the magnetic field at a distance x from the centre of the coil, where (x/R = 3/4), is :

✅ Yes |
✅ Yes |

✅ Yes |
✅ Ratio with B_center |

|
Final target |
Field at axis (x = r/2) |
Ratio B_center / B_x |
✅ |
Conclusion: Both questions test the concept of magnetic field due to a circular current-carrying coil. The predicted question calculates B along the axis, and the actual question compares that with B at center using a given x/R value. Conceptually and mathematically, they are highly similar.
Predicted Question
Match List I with List II:

List I |
List II |
|
A. Isothermal Process |
I. Work done by gas decreases internal energy |
|
B. Adiabatic Process |
II. No change in internal energy |
|
C. Isochoric Process |
III. The heat absorbed goes partly to increase internal energy and partly to do work |
|
D. Isobaric Process |
IV. No work is done on or by the gas |
Actual Question Jee Mains 2nd April 2025 Shift 1
Which of the following statement(s) is/are correct for the adiabatic process?
(A) Molar heat capacity is zero
(B) Molar heat capacity is infinite
(C) Work done on gas is equal to increase in internal energy
(D) The increase in temperature results in decrease in internal energy

Conclusion: Both questions assess conceptual understanding of thermodynamic processes, especially adiabatic behavior. The predicted question uses matching format while the actual question uses multiple true/false choices, but both check the same foundational understanding.
Be Smart About PYQs
A word of caution: blindly solving 10 years of papers equals 18,000+ questions — and that’s overwhelming.
Instead, use AI + clustering techniques (like what we do at Learne2i) to:
- Focus on highly recurring patterns
- Practice targeted question sets
- Predict future matches more reliably
