Questions with model answers

What each question tests, the first step of a good answer and the follow-ups to expect.

Fresher

You will sit AMCAT in three weeks and the eLitmus pH Test a week after that. Using what each test publishes about its timing, its penalties and its scoring, how do you shape your practice for the two?
What it tests

Reading published rules, turning seconds per question, penalty rules and scoring into practice decisions, and handling a penalty whose formula is not published.

First step

Put the rules side by side. AMCAT gives each module its own time, 60 seconds a question for English and 75 for its Quantitative Ability (Tech) and Logical Ability modules, and its syllabus page states no penalty. eLitmus gives about 120 seconds a question, prints the formulae, grades questions by difficulty and penalises wrong answers by an unpublished rule that weighs accuracy.
Follow-ups
- Which practice serves both tests?
- How do you practise for a penalty whose formula you do not know?
- What changes in the last three days before each test?

A test gives each section a fixed 40-minute clock and does not let you switch sections. After 28 minutes you have answered every reasoning question you can solve. How do you use the 12 minutes left, and what would change if the whole test ran on one clock?
What it tests

Using time inside a sectional clock, ordering the work that is left by its value, and comparing the value of a minute across sections when time can move.

First step

With sectional clocks the 12 minutes cannot move to another section, so every one of them is worth spending here. List what is left: questions you skipped after partial work, questions you never read, and answers you marked as unsure, then take them in that order.
Follow-ups
- Should you guess the questions you could not do?
- How would you practise for this?
- What changes if the section has no negative marking?

Two minutes remain in a section marked +2 for a right answer and −0.50 for a wrong one, and four questions with four options each are unread. Do you guess all four blind, read one first, or leave them? Justify it with expected marks and the spread.
What it tests

The value of a blind guess, the spread of a few guesses, and weighing a worked answer against blind guesses when time is short.

First step

Price each choice. A blind guess is worth (1/4)(2) − (3/4)(0.5) = +0.125 marks, so four are worth +0.5 on average, anywhere from −2 if all are wrong to +8 if all are right. Reading one question costs most of the time but can turn a one-in-four chance into a worked answer worth up to 2 marks.
Follow-ups
- What if the scheme were +3 for a right answer and −1 for a wrong one?
- How likely is it that the four blind guesses lose marks?
- Does the answer change in a test you may retake, where only your best score counts?

Over three mocks marked +2 / −0.50, your guesses between two remaining options were right 14 times in 40. Should you keep guessing in that situation, and what does the 35 % tell you about your eliminations?
What it tests

Comparing measured accuracy with the break-even chance, reading what a rate below one half says about eliminations, and judging a small sample.

First step

Compare 14/40 = 35 % with two rates. The break-even chance of +2 / −0.50, 0.50 ÷ (2 + 0.50) = 20 %, decides whether these guesses pay. The 50 % that a fair pick between two options would give tells you how often the right answer survived your eliminations.
Follow-ups
- How sure can you be of a rate measured on 40 guesses?
- How would you trace which eliminations fail?
- What would the same records be worth under the 1-mark GATE MCQ rule?

Your diagnostic shows quantitative at 80 %, reasoning at 40 % and verbal at 60 %. You have three weeks and 9 hours a week before a campus test. Build the weekly split of hours, defend it, and say what you would leave out.
What it tests

Turning accuracy into hours, protecting time for review and a mock, making trade-offs explicit, and changing the plan as results change.

First step

Fix the frame before splitting: 27 hours in all, 1 hour every week for the error log, and the last week for a full mock, its analysis and mixed timed sets. That leaves 8 hours in each of weeks 1 and 2: give every section its half-hour floor, then share the rest by error rate, 20, 60 and 40 points.
Follow-ups
- A timed set in week 1 shows reasoning at 60 %. How does week 2 change?
- How do you use week 3?
- Which topics does this plan leave out, and is that acceptable?

After two mocks, your error log shows that 9 of your 20 lost questions are calculation slips in data interpretation. What do you change in your practice, and how will you know that the change worked?
What it tests

Confirming a cause before fixing it, matching the fix to slips rather than to a method gap, and setting a check that can be measured.

First step

Confirm the cause first: re-solve the nine questions untimed. If you now get them right, the method is sound and the cause really is slips. Then look at where the slips happen, such as percentages of large numbers, units like thousands and lakhs, or reading the wrong row of a table.
Follow-ups
- What if you get them wrong again untimed?
- How many mocks do you need before you judge the fix?
- Would speed drills help or hurt?
