Q1. A teacher already has a finished question paper and wants model answers written against each mark. Which Veda feature does this?

Beginner
A Add more from the source panel B Paper Solver on the Home screen C MCQ Practice from the chat menu D Turn this chat into… in the ⋮ menu
Show answer & explanation

Paper Solver on the Home screen

Paper Solver converts an existing question paper into model answers by marks. It is the reverse of paper creation, which happens through Turn this chat into….

Q2. Which of these is NOT one of the five starting sources for creating a new paper in Veda?

Beginner
A A topic typed into chat B A pasted set of class notes C A blank page with no input D A PDF, photo or link
Show answer & explanation

A blank page with no input

Veda builds papers from a topic, pasted notes, a PDF, a photo, or a link. A blank page with no source gives the tool nothing to work from.

Q3. A student wants level-by-level questions where every single answer is explained. Which output should they pick?

Beginner
A Paper Solver B MCQ Practice C The Quizzes tab D AI Quiz
Show answer & explanation

MCQ Practice

MCQ Practice gives level-by-level questions with every answer explained. AI Quiz is for scoring a class, and Paper Solver converts an existing paper into model answers.

Q4. Where does the output of AI Quiz appear?

Beginner
A Inside the ⋮ menu B In the Quizzes tab C In the Home screen only D In the Paper Solver panel
Show answer & explanation

In the Quizzes tab

AI Quiz builds a scored quiz for a class, delivered live or as homework, and it lives in the Quizzes tab.

Q5. A teacher wants to add flashcards, notes and a game on top of the same source PDF they already used for a paper. What should they use?

Beginner
A Paper Solver B Add more C The Quizzes tab D Share or assign
Show answer & explanation

Add more

Add more lets you layer flashcards, notes, or games onto the same source, so one PDF can become a full study kit.

Q6. **Paper Solver** converts an existing question paper into model answers by marks; it does **not** create a new paper — for creation you use **Turn this chat into…**.

Beginner
A True B False
Show answer & explanation

True

**Paper Solver** converts an existing question paper into model answers by marks; it does **not** create a new paper — for creation you use **Turn this chat into…**.

Q7. In the Class 8 CBSE Maths sample paper, Sections C and D together carried what share of the total marks?

Intermediate
A About 24% B About 48% C About 80% D About 12%
Show answer & explanation

About 48%

Section C carried 24% and Section D carried 24%, so together they accounted for 48% of the 50 marks — deliberately, so multi-step questions dominate.

Q8. A student pastes a Class 8 CBSE Maths syllabus covering Cubes & Cube Roots, Coordinate Geometry, Factorisation and Algebraic Identities. Why will Veda not include a trigonometry question?

Intermediate
A Because the Quizzes tab filters by class B Because the source acts as the truth boundary C Because trigonometry is too hard for Class 8 D Because Paper Solver blocks extra chapters
Show answer & explanation

Because the source acts as the truth boundary

The source you provide is the truth boundary. If the syllabus does not list trigonometry, Veda will not pull it in from outside the given chapters.

Q9. A teacher needs a graded score for a live class session. Which output fits that need best?

Intermediate
A MCQ Practice B Paper Solver C Add more D AI Quiz
Show answer & explanation

AI Quiz

AI Quiz builds a scored quiz for a class, live or as homework. MCQ Practice is for self-paced learning with explanations, not for grading.

Q10. A student writes only the correct final answer in Section C and skips all working. What happens under the marking scheme?

Intermediate
A They get full marks for the answer B They gain marks for brevity C They lose the 2 step marks and keep 1 D They lose all 3 marks for the question
Show answer & explanation

They lose the 2 step marks and keep 1

Section C awards 2 marks for steps and 1 mark for the final answer. Skipping the steps costs the 2 step marks, leaving only the answer mark.

Q11. Which statement about 'extreme hard' papers in Veda is correct?

Intermediate
A They use multi-step methods within the same syllabus B They pull in content from higher classes C They replace MCQs with only 1-mark questions D They drop the marking scheme entirely
Show answer & explanation

They use multi-step methods within the same syllabus

Difficulty is about how many steps a student must chain, not about obscure or out-of-syllabus content. The same chapter can yield an easy or an extreme-hard question.

Q12. A tutor wants one paper that an entire class can attempt at home. Which Veda action makes this possible?

Intermediate
A Switch to MCQ Practice mode B Use Add more to attach notes C Open Paper Solver on the Home screen D Share or assign the paper to a class
Show answer & explanation

Share or assign the paper to a class

Anything you make can be shared or assigned to a class, which is what turns one generated paper into a class-wide resource.

Q13. Assertion (A): A paper where every question is worth 1 mark tests recall rather than understanding. Reason (R): The marks architecture of a paper determines its difficulty profile.

Advanced
A A is false but R is true. B Both A and R are true, and R correctly explains A. C Both A and R are true, but R does not explain A. D A is true but R is false.
Show answer & explanation

Both A and R are true, and R correctly explains A.

Both statements are true, and the reason explains the assertion: because the marks architecture sets the difficulty profile, a paper built entirely of 1-mark items can only test direct recall, not multi-step understanding.

Q14. Consider these statements about Veda's paper tools: I. Paper Solver creates a brand-new paper from a topic. II. Turn this chat into… is the entry point for both AI Quiz and MCQ Practice. III. AI Quiz output lives in the Quizzes tab.

Advanced
A II and III only B I and II only C I and III only D I, II and III
Show answer & explanation

II and III only

Statement I is false: Paper Solver converts an existing paper into model answers, it does not create a new one. Statements II and III are both correct.

Q15. A teacher wants a paper that is genuinely hard but still fair to the syllabus. Which combination is the best choice?

Advanced
A Start from a vague topic name and add Class 10 questions B Start from a photo and make every question 1 mark C Start from the syllabus PDF and weight Sections C and D heavily D Start from a link and skip the marking scheme
Show answer & explanation

Start from the syllabus PDF and weight Sections C and D heavily

Starting from the syllabus PDF keeps the paper inside the truth boundary, and weighting Sections C and D heavily raises difficulty through multi-step demand rather than out-of-syllabus content.

Q16. A student says: 'I tapped Paper Solver but it did not make me a new paper.' What is the correct explanation?

Advanced
A Paper Solver only works after a quiz has been generated B Paper Solver needs a photo rather than a topic C Paper Solver is only available inside the Quizzes tab D Paper Solver solves an existing paper; creation needs Turn this chat into…
Show answer & explanation

Paper Solver solves an existing paper; creation needs Turn this chat into…

The two tools run in opposite directions. Paper Solver goes paper → answers, while Turn this chat into… goes content → paper. Tapping the wrong one explains the confusion.

Q17. A rectangular plot has vertices at the points $A(2, 3)$, $B(2, 7)$, $C(6, 7)$, and $D(6, 3)$. If a cube with a side length of 4 units is placed on top of this plot, what will be the coordinates of the vertex directly above point $A$?

Advanced
A (2, 3, 0) B (2, 3, 7) C (2, 3, 4) D (2, 3, 8)
Show answer & explanation

(2, 3, 4)

The vertex directly above point $A(2, 3)$ will maintain the same $x$ and $y$ coordinates but will have a $z$ coordinate equal to the height of the cube, which is 4 units. Therefore, the correct coordinates are $(2, 3, 4)$.
