What the paper isFifty questions, two marks each
Meteorology is one of the two DGCA papers set as 50 questions at 2 marks each rather than 100 at one. That single fact changes how it should be sat: every question is worth double, so a guess costs twice as much and a question skipped in a hurry is two marks, not one.
You have 2 hours for 50 questions — about 144 seconds each. That is generous by DGCA standards, and it is why leaving marks on the table in this paper is almost always a knowledge problem rather than a clock problem.
How the paper is builtDrawn from the whole subject, every time
The 50 questions are drawn at random from all 1,527 in the bank, across every one of the 45 chapters — not from a fixed sample paper. Sit it twice and you get two different papers, which is the only way a mock test tells you anything after the first attempt.
It also means the draw is weighted the way the bank is: the chapters DGCA sets most heavily are the chapters that hold the most questions, so a paper assembled this way looks like a real one without anybody having to hand-pick it.
What it does not doNothing is revealed until you submit
In exam mode the answer key is held server-side for the whole sitting. No option is marked, no explanation opens, and no running score is shown — because a paper that tells you question 4 was wrong has taught you something about question 27, and the estimate it produces is worthless.
You can answer in any order, change an answer as often as you like, and use the navigator to find what you skipped. One countdown runs for the whole paper.
What to do with the resultA mark, then the chapters behind it
Submitting marks the paper out of 100 against the 70 pass, then breaks the result down by chapter — so a fail reads as "stability and thunderstorms" rather than as a number. Every wrong answer drops into the mistakes bank, which can be practised on its own.
Test and exam answers also move the readiness engine, an Item Response Theory model that predicts your mark on a fresh paper with a confidence interval. Practice answers deliberately do not move it: revising with the answer visible is not evidence of anything.
