Bhai, pehle hall ticket. If your code is BE02000011 or BE02R00011, this post is only half useful (those syllabi swap in matrices and complex variables). This write-up is for 3110015.

Paper shape (unchanged across the 9)

• 3 hours
• 70 marks end-sem + 30 internal
• 5 questions x 14, mostly (a) 3 + (b) 4 + (c) 7
• Q.1 has no OR. Q.2 has an OR only on (c). Q.3 to Q.5 have a full OR
• Simple non-programmable scientific calculator: stated in 8 of 9 papers (Winter 2025 instruction list skips that line, so confirm with your centre)

Unit weightage (official syllabus)

That "2-hour" Fourier integral unit? It still appeared in all 9 papers. Classic GTU.

The 9/9 list

Green's theorem, div/curl checks, Fourier integral, Laplace IVP, variation of parameters, undetermined coefficients, Euler-Cauchy, p/Clairaut-type first-order equations, and power series at an ordinary point.

Also strong: linear/Bernoulli (8/9), Laplace of f(t)/t (7/9), convolution (7/9), exact DE (7/9), singular-point classification (7/9).

Copy-paste repeats (same equation, different session)

• y'' + y = sin x by variation of parameters: Winter 2022 and Summer 2024
• Power series of y'' + xy = 0: Winter 2022 and Summer 2025
• ye^x dx + (2y + e^x) dy = 0: Winter 2024 and Summer 2025
• Rodrigues' formula for P_n(x): Summer 2023 and Summer 2026
• Fourier cosine integral of e^(-kx): Summer 2022 and Summer 2024

A 10-day plan

• Days 1-2: Higher order ODEs (26%). VOP, undetermined coefficients, Euler-Cauchy.
• Day 3: First order ODEs. Exact, linear/Bernoulli, p/Clairaut.
• Days 4-5: Laplace + Fourier integral. IVP, f(t)/t, convolution, then e^(-kx) type Fourier.
• Day 6: Vector calculus. Green's until you can verify it half-asleep (Q.1(c) in 8 of 9).
• Days 7-8: Series solutions. Power series and singular points first, then Frobenius / Bessel / Legendre.
• Days 9-10: Two full papers, timed at 3 hours. Redo only mistakes.

Exam kal hai and it is 11 PM? Do the 9/9 rows. No promises. That is where the counts point.

Bhai, Physics ka paper alag hi game hai. Maths ke baad Physics dene wale students ek hi galti karte hain: time ka hisaab. Chalo ek ek karke dekhte hain.

1. Time: 2.5 hours, not 3

• GTU Physics paper: 2.5 hours (10:30 AM to 1:00 PM or 2:30 PM to 5:00 PM)
• Maths paper: 3 hours
• Marks in both: 70

Same 70 marks, 30 minutes less. So when you practise, set your timer to 2.5 hours, not 3.

2. Structure: 5 questions x 14 marks

Most questions split as (a) 3 + (b) 4 + (c) 7. A simple non-programmable scientific calculator is allowed.

3. Choice: where the OR lives

• Q.1: no OR at all, so it is fully compulsory
• Q.2: OR only on part (c)
• Q.3, Q.4, Q.5: full OR

Plan your revision around this. Q.1 has no escape, so cover the basics for it first.

4. Same question, different code

Some questions jump across subject codes. Two examples from the guide:

• The ultrasonic echo sum (0.09 MHz source, pulse comes back after 0.55 s, speed of sound in water 1800 m/s) appeared in 3110011 (S2022, S2023) and again in BE01000021 (W2024, S2026).
• The SHM question "show that KE + PE stays constant" appeared in 3110011 W2022 and in BE01000021 W2024 and W2025.

So if you are on the new code, the older 3110011 papers are good extra practice for properties of matter, acoustics and ultrasonics.

5. Check your subject code first

Syllabus differs between 3110011, 3110018 and BE01000021 (BE01R00021 has the same units and weightage as BE01000021). Before solving any paper, match the code on it with the code on your hall ticket.

6. Where to get the papers

Open gtu.ac.in/Download1.aspx, pick the session, pick BE, and search your subject code. One more thing: GTU's repository serves papers, and GTU Hero did not find official solution PDFs there.

The disclaimer

Past repetition is a pattern, not a promise. GTU can change the paper any time. Use these notes to set priorities, not to skip chapters.

Full counts, unit weightage and per-code plans: GTU Hero's Physics PYQ guide. If you only want to browse old papers, start from GTU Hero papers.

Disclosure: I work on GTU Hero.

The three codes

3110014 Modules: calculus, sequences and series, Fourier series, multivariable calculus, multiple integrals and matrices. This version is worth 5 credits.

BE01000041 (w.e.f. 2024-25) Fourier series and matrices are not part of this one. It is worth 4 credits.

BE01R00041 (w.e.f. 2025-26) The same five modules as BE01000041. Only the hours and weightage are different.

Quick summary in Hinglish: code galat hua toh Fourier ratne mein time waste ho sakta hai, isliye pehle code check kar lo.

The paper format

Across the 13 official papers we looked at (Summer 2022 to Summer 2026), the format is the same: 3 hours, 70 marks, and 5 questions of 14 marks each. Each 14 mark question is split into 3 + 4 + 7.

How to use old papers if your code changed

Papers of 3110014 still help for calculus, series, multivariable calculus and multiple integrals. Those modules are part of the newer codes too, so solving those questions is still useful practice.

But if you are on BE01000041 or BE01R00041, skip Fourier series and matrices questions from the old 3110014 papers. They are not in your syllabus, and the time is better spent elsewhere.

A simple routine:

1. Find your subject code on your syllabus or admit card.
2. Open the old paper and note which module each question belongs to.
3. Solve only the questions from modules your code includes.
4. Keep the paper format in mind (5 questions, 14 marks each, split 3 + 4 + 7) so you practise with the right time and marks.

Where to find the papers

You can browse the papers on GTU Hero question papers.

Good luck with the exam, and double check your code first.

First, check your subject code

Programming for Problem Solving (PPS) appears under codes such as 3110003 and BE01000121 in different B.E. course listings. Old papers are only useful if they match your code and syllabus, so check your hall ticket first. Then use the official GTU question paper repository: pick the exam session, pick your course, search by subject code and save the PDF.

The practice list

This is a practice priority list built from common intro C topics and the available GTU PPS papers. It is not a statistical ranking.

1. Even or odd. if-else and the % operator. An even-or-odd algorithm was asked in the Winter 2025 paper for 3110003.
2. Factorial. Do both the loop version and the recursive version. 5! = 120.
3. Prime check. Test with 1, 2, 7, 9 and 15. Bhai, 1 is not prime.
4. Fibonacci series. First six terms: 0 1 1 2 3 5.
5. Sum of digits. % 10 gives the last digit, / 10 removes it. Sum of digits of 145 is 10.
6. Reverse a number and palindrome check. 121 and 1331 should pass.
7. Largest of three. Make sure it still works when two or all three inputs are equal.
8. Armstrong number. 153 = 1^3 + 5^3 + 3^3.

How to use this list

Write the algorithm and flowchart too, not only the code. Trace the output by hand, then run it. Ratta maarne se kuch nahi hoga, because the same concept can come back with different wording.

Formula kya hai?

GTU ke official conversion certificate me formula yeh hai:

Percentage = CPI x 10

Matlab CPI 8.0 hai to percentage 80% hoga, aur CPI 7.4 hai to 74%. Koi extra adjustment factor nahi lagta.

CPI aur SPI me farak

CPI ka full form Cumulative Performance Index hai. GTU me ise wahi cheez samjho jo baaki universities me CGPA kehte hain. SPI sirf ek semester ka hota hai, aur CPI saare semesters ka credit weighted average hota hai. Dono 10 point scale pe hain, to dono pe CPI x 10 jaisa hi formula lagta hai.

Examples

• CPI 8.2 x 10 = 82%
• CPI 7.43 x 10 = 74.3%

Dhyan rahe, 7.43 ko pehle 7.4 mat banao. Decimal ko round karne se pehle hi multiply karo, warna accuracy kam ho jaati hai.

Ek common galti: CBSE wala 9.5

Kai students CGPA x 9.5 use kar lete hain, jo CBSE ka formula hai. GTU ye use nahi karta. Agar CPI 8.0 pe 9.5 lagaoge to 76% milega, jabki sahi answer 80% hai. Job form ya admission form me ye 4 percent ka farak kaafi bada ho sakta hai.

Ek aur cheez yaad rakho

CPI x 10 ek approximation hai. Agar kisi form me "aggregate percentage of marks" maanga hai, to wo actual marks ka total divide total maximum marks hota hai, aur wo CPI x 10 se kam aa sakta hai. Isliye form dhyan se padho.

Disclosure: I built GTU Hero, a site that shows GTU previous-year papers with repeated questions highlighted. This post is about the counting exercise behind it.

Students at Gujarat Technological University circulate "IMP question" lists before every exam, and most of them do not say where the list came from. I wanted a boring, checkable answer to one question: if you take the official papers for a subject and count, what actually repeats?

So I counted 44 official papers from GTU's own question paper repository across three first-year subjects (Mathematics-1, Mathematics-2 and Physics, Summer 2022 to Summer 2026). I extracted the text with pdftotext, tagged every sub-question by topic, and counted a topic once per paper if it showed up anywhere in it.

A few results:

• Mathematics-2 (3110015): 9 of the 22 tagged topics appeared in all 9 papers. Green's theorem sat in the compulsory Q.1(c) in 8 of them.
• Syllabus hours are not exam frequency. The Fourier integral unit gets 2 teaching hours in the official syllabus and appeared in all 9 papers.
• Exact repeats cross subject codes. One Physics numerical (ultrasonic source at 0.09 MHz, pulse back after 0.55 s) appeared in two 3110011 papers and two BE01000021 papers.

The messy parts were more interesting than the counting: a PDF where pdftotext returned only 587 characters because the questions were images, one subject name with several codes, and the rule for what counts as a "topic".

The full write-up, with the code and everything that broke, is on DEV: https://dev.to/offpage_prince/how-i-count-repeated-questions-across-44-gtu-exam-papers-and-what-broke-439o

Corrections to my tagging are welcome as issues.

Past repetition is a pattern, not a promise. GTU can change a paper any time.
