This subject without a doubt is all about concepts, if you know something then only you can answer something. There are no guess works. For this you need to study each phenomenon in detail. Questions directly come from the concept. Here, take an example
Consider the following statements:
1. Jet streams occur in the Northern Hemisphere only.
2. Only some cyclones develop an eye.
3. The temperature inside the eye of a cyclone is nearly 10°C lesser than that of the surroundings.
Which of the statements given above is/are correct?
(a) 1 only
(b) 2 and 3 only
(c) 2 only
(d) 1 and 3 only
This question is from 2020 Prelims and asks you following questions indirectly to answer it correctly:
What are jet streams and how do they form? In which hemisphere and on which latitude do they flow?
How are cyclones formed? What are the basic conditions for the formation of the cyclone? How does pressure and temperatures varies in it?
Hence, a question from atmosphere chapter which demands you to have details of the phenomena.
KPS Geography booklet will help you clear each and every doubt and will make you understand these concepts in detail.
