Hello,

There are a lot of privates sites which have pdfs of previous year ICAR papers,you can find them easily when you do a google search.I also recommend you to search for 'icar previous year questions' on youtube, as you will get solutions of those questions as well and links to download the questions pdfs and answer pdfs are mostly given in the description box too many a times.That will also prove beneficial to you incase you get stuck at a question.

You can also find mock papers to practice in this link- https://university.careers360.com/articles/icar-aieea

All the best!
