Sample AP ECET Practice Questions

Try these sample questions to test your AP ECET exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1The inverse of the matrix [[2, 1], [5, 3]] is:

A.[[3, -1], [-5, 2]]

B.[[3, 1], [5, 2]]

C.[[-3, 1], [5, -2]]

D.[[2, -1], [-5, 3]]

Explanation: For A=[[a,b],[c,d]], A⁻¹=(1/(ad−bc))[[d,−b],[−c,a]]. det(A)=6−5=1, so A⁻¹=[[3,−1],[−5,2]].

2If A = [[1, 2], [3, 4]] and B = [[2, 0], [1, 3]], then AB equals:

A.[[4, 6], [10, 12]]

B.[[2, 0], [3, 12]]

C.[[5, 6], [10, 12]]

D.[[4, 0], [10, 12]]

Explanation: Row–column products: 1·2+2·1=4, 1·0+2·3=6, 3·2+4·1=10, 3·0+4·3=12. So AB=[[4,6],[10,12]].

3Using Cramer’s rule for x + y = 3 and 2x − y = 0, the value of x is:

A.1

B.2

C.3

D.0

Explanation: D=|1 1; 2 −1|=−3. Dx=|3 1; 0 −1|=−3. x=Dx/D=1.

4In the partial-fraction decomposition of (x+1)/((x−1)(x−2)), the coefficient of 1/(x−1) is:

A.−2

B.2

C.−1

D.1

Explanation: Write A/(x−1)+B/(x−2). At x=1: (1+1)/(1−2)=A ⇒ A=−2.

5sin 75° equals:

A.(√6 + √2)/4

B.(√6 − √2)/4

C.(√3 + 1)/2

D.√3/2

Explanation: sin(45°+30°)=sin45 cos30+cos45 sin30=(√2/2)(√3/2)+(√2/2)(1/2)=(√6+√2)/4.

6If tan θ = 3/4 and θ is acute, then sin θ is:

A.3/5

B.4/5

C.3/4

D.5/3

Explanation: Sides 3-4-5: sin θ = opposite/hypotenuse = 3/5.

7The principal argument of −1 + i√3 is:

A.2π/3

B.π/3

C.π/6

D.π/2

Explanation: Point is in quadrant II with reference angle π/3, so arg = π − π/3 = 2π/3.

8The modulus of 3 − 4i is:

A.5

B.7

C.1

D.25

Explanation: |a+bi|=√(a²+b²)=√(9+16)=5.

9The equation of the circle with centre (2, −3) and radius 5 is:

A.(x−2)² + (y+3)² = 25

B.(x+2)² + (y−3)² = 25

C.(x−2)² + (y−3)² = 5

D.(x−2)² + (y+3)² = 5

Explanation: Standard form (x−h)²+(y−k)²=r² with (h,k)=(2,−3), r=5 ⇒ (x−2)²+(y+3)²=25.

10The focus of the parabola y² = 16x is:

A.(4, 0)

B.(0, 4)

C.(8, 0)

D.(2, 0)

Explanation: y²=4ax with 4a=16 ⇒ a=4. Focus is (a,0)=(4,0).

About the AP ECET Exam

AP ECET (APECET) is Andhra Pradesh’s state-level common entrance test for diploma holders and B.Sc. (Mathematics) graduates seeking lateral entry into the second year of B.E./B.Tech./B.Pharmacy programmes. JNTU Anantapur conducts the exam on behalf of APSCHE as a 3-hour computer-based test of 200 objective questions. Engineering diploma candidates answer common Mathematics (50), Physics (25), and Chemistry (25) plus a 100-mark branch-specific engineering paper. Ranking requires 25% aggregate (50/200) except SC/ST candidates, who have no minimum qualifying marks for ranking.

AP ECET Study Tips from Top Performers

1Weight practice to the official split: half your timed sets should be Mechanical branch items, then Mathematics, then Physics/Chemistry equally

2Drill diploma matrices, calculus, and first-order DEs daily — Mathematics alone is 50 marks

3For Mechanical, alternate SOM/TOM numericals with manufacturing and thermal conceptual sets so you do not neglect the 100-mark branch paper

4Use full 180-minute CBT mocks (200 Q) because there is no negative marking — build completion speed without careless slips

5Revise only the official APECET-2026 common and Mechanical PDFs from cets.apsche.ap.gov.in/ECET rather than mixing EAPCET (intermediate) syllabi

Frequently Asked Questions

What is the AP ECET 2026 exam pattern for Engineering diploma holders?

The Engineering stream is a 3-hour CBT with 200 objective questions for 200 marks: Mathematics 50, Physics 25, Chemistry 25, and Engineering (branch paper) 100. Each correct answer carries 1 mark and there is no negative marking. The question paper is in English. Each engineering branch has a separate 100-mark paper.

What is the AP ECET 2026 registration fee?

As per the official APECET-2026 Registration Fee Details PDF on cets.apsche.ap.gov.in/ECET, the fee is Rs. 800 for OC, Rs. 750 for BC, and Rs. 700 for SC/ST categories, payable online.

What are the qualifying marks for an AP ECET rank?

Candidates need 25% of the aggregate marks (50 out of 200) to obtain a rank. SC/ST candidates have no minimum qualifying marks for ranking. Ranks are prepared branch-wise for Engineering; ties use Engineering, then Mathematics, then Physics marks, then age at admission.

Who conducts AP ECET and who is eligible?

JNTU Anantapur conducts APECET on behalf of APSCHE. Eligible candidates are Indian nationals belonging to Andhra Pradesh who hold a diploma in Engineering/Technology/Pharmacy (or equivalent) or a 3-year B.Sc. with Mathematics, with at least 45% marks (40% for BC/SC/ST).

Which Mechanical Engineering topics appear in AP ECET?

The official Mechanical syllabus covers workshop technology and drawing conventions, production technology and CAM/CNC, engineering materials and solid mechanics, theory of machines and machine design, thermodynamics and heat power, hydraulics and fluid power, steam boilers/nozzles/turbines/condensers, refrigeration and air conditioning, industrial management, energy sources and power plants, and e-vehicle technology.

Is there negative marking in AP ECET?

No. Each question carries one mark for a correct response. Incorrect or unattempted questions do not reduce the score, so candidates should attempt all items after eliminating options where possible.

What is the official website for AP ECET 2026?

The official portal is https://cets.apsche.ap.gov.in/ECET. Syllabus PDFs, the instruction booklet, fee details, hall tickets, keys, and results are published there. Helpdesk: helpdeskapecet@apsche.org.
