At first it might appear as a difficult subject because most of us are not in habit of reading the newspaper (you only have to read the op-eds and not the whole paper), and we do not understand the nature of the questions (they ask about policy problems and structural issues and not day to day problems). And then we also hear that one has to read some 10 newspapers. All these things make us feel that it is a difficult subject. However, as you go ahead in your preparation you get command on the subject. Reading dawn editorials for six months will build your knowledge a lot. Other than that, watching Zara Hut Key, and Al Jazeera Inside story will be more than enough.

The reason that a lot of candidates score well in the subject is because it does not require a lot of analysis like IR or PA will. And a lot of candidates have in past said that they only prepare for CA and complement PA prep with that. Furthermore, CA is the most important subject as we see that the examiner is making the optional papers out of current events. In 2019 ICC question came in ILaw, and it was inspired by a statement of John Bolton. So all the successful candidates work extra hard on CA because it will help in optional, another reason for more marks.
If you are having trouble in CA rn, then dw by the end of your prep you will be an expert. Read Al Jazeera and Dawn op-eds and watch them as well. Furthermore, there are some YT channels that will help you. I am adding the links:

VOX (watch their political and social videos)
https://www.youtube.com/user/voxdotcom

Hank and John Explain
https://www.youtube.com/watch?v=hIGt...u7ACeVc7qOn8Dq

This world now (few of their videos have mistakes so look into the comments as well)
https://www.youtube.com/user/TestTubeNetwork

Caspian Report (all facts for background knowledge)
https://www.youtube.com/user/CaspianReport

This is an Indian UPSC YT Channel. It has some very useful and informative videos on CA
https://www.youtube.com/channel/UCrC...S6rQ/playlists

Daily Show (don't read or watch any american newspaper or show. Daily show is a good take on domestic American politics, but not the international one. Trevor does some really good interviews like the one with IMF head, do watch them. He talks about race and other issues as well. So this is a complete package on US domestic politics)
https://www.youtube.com/channel/UCwW...2TyRM4Wstoq8HA

Patriot Act with Hasan Minhaj is another good source
https://www.youtube.com/channel/UCar...9QY-fy-Z6apIDQ

Geography Now (a lot of info on a lot of countries. This will increase your knowledge a lot. Do Pakistan's neighbors from this)
https://www.youtube.com/channel/UCmm...Pw1HL2lq6H4ffA

This channel makes summary of a lot of current affairs issues, but it is only facts. Use them for info only
https://www.youtube.com/channel/UCZA...ajmehOw/videos

Search "issue" explain and there will be multiple short videos explaining it all
If you think that videos are too slow then watch in 2x

Also read Munir Akram in Dawn. At least his articles from 2013 (they are not a lot)
If you are short on time then use this website https://ttsreader.com/ paste the article text in it and it will read everything to you. That will be quick and it also has speed options. Only one problem: it is a robot reading to you.

If you are starting now then first of all go online and read last 6 months dawn. Make notes in a word doc. Once you have all that info, you will do well in IR. There is a Sir Fareed in NOA, and he has a good CA book (much of which is copied), but if you have not been in touch with newspaper for years, then it is a good place to start. Use the syllabus and google every topic in it, then you will be able to do well in CA as well.


then lets come to your answer presentation
you need to add analysis that is simply breaking down the events

If you are discussing US-Iran issue the you have to break down the events.
Trump’s withdrawal of the deal (event)
Wants regime change
Pompeo and Bolton are not friendly to Muslim nations
Pompeo is anti Islam
Israel has an issue with Iran’s nuke power capacity and Iran supports Hezbollah
KSA, a close US ally, has a cold war with Iran and they are against each other in Yemen.
Trump sees this as Obama’s deal and he wants to undo it. He has a very personalized way of working and wants to redo North Korea with Iran.

You can add more points here. Higher marks come with your ability to break down the events and see them from different angles. Like here we saw from the perspective of Trump's team, his own preference, geopolitics, and the US allies. In that Indian YT channel's link there is a video on this in detail where they discuss the scientific aspect of Trump's side. Have a look at that as well.

I hope that this helps.
