Frequently Asked Questions

1.How many questions are in the AP EAMCET 2021 20th August Evening Shift paper?

This paper has 160 questions in total - 40 from Chemistry, 80 from Mathematics, and 40 from Physics.

2.Can I practise questions from just one subject?

Yes. Use the Chemistry, Mathematics, and Physics tabs at the top of the page to jump directly to that subject's question set within this shift.

3.Is this the same paper for all students who appeared in the evening shift?

AP EAMCET uses different question sets across shifts and sessions to maintain exam integrity, so this page reflects the specific paper administered in the 20th August 2021 evening shift.

4.Where can I find the morning shift paper for the same date?

The AP EAMCET 2021 20th August Morning Shift paper is listed separately - you can switch to it from the "AP EAMCET Paper Wise PYQs" panel, under AP EAMCET 20th August 2021.

5.How is the AP EAMCET 2021 20th August Evening Shift paper structured?

The AP EAMCET 2021 20th August Evening Shift paper on MARKS has 160 questions, organised by subject:

  • Chemistry: 40 questions - 40 single-correct.
  • Mathematics: 80 questions - 80 single-correct.
  • Physics: 40 questions - 40 single-correct.
6.How difficult is the AP EAMCET 2021 20th August Evening Shift paper?

Each question on MARKS carries a difficulty rating. Of the 160 rated questions in this paper, 71 (44%) are easy, 65 (41%) are medium and 24 (15%) are hard. Subject wise:

  • Chemistry: 26 easy, 13 medium, 1 hard
  • Mathematics: 27 easy, 35 medium, 18 hard
  • Physics: 18 easy, 17 medium, 5 hard
7.Which chapters were asked the most in the AP EAMCET 2021 20th August Evening Shift paper?

The chapters with the most questions in each subject were:

  • Chemistry: Classification of Elements and Periodicity in Properties (4), Chemical Bonding and Molecular Structure (3), and Structure of Atom (3).
  • Mathematics: Circle (7), Straight Lines (7), and Vector Algebra (7).
  • Physics: Electrostatics (3), Work Power Energy (3), and Dual Nature of Matter (2).
8.Where can I find the solutions for the AP EAMCET 2021 20th August Evening Shift paper?

Open any question on this page. Its page shows the correct answer and, where one is available, the worked solution. A downloadable PDF of the whole shift is coming soon.

9.How should I use the AP EAMCET 2021 20th August Evening Shift paper to check my preparation?

Set a timer, attempt the 160 questions as you would in the exam, and only then open the answers. Note which subjects and chapters cost you the most marks, and revise those first using the chapter-wise practice for AP EAMCET. Repeating this with other papers shows whether the same weak spots keep coming back.

10.Will the AP EAMCET 2021 20th August Evening Shift paper help me prepare for AP EAMCET 2027?

Yes. Every past paper shows the question styles and topics AP EAMCET has asked before, and a solved paper gives you a realistic benchmark for speed and accuracy. Use it along with the other papers to spot the chapters that keep returning.
