Hi Akshay,
You should be able to, but the books usually give quite good information, especially when it comes to programming.
There are 16 modules I found on the Microsoft Learn regarding C#, you'll find them here:
https://docs.microsoft.com/en-us/learn/browse/?roles=developer&term=C%23
There are however lots of free material on the Internet, like guides, videos, documentations that you may also use
for free.
I would suggest you go through the "Skills measured" section of the exam page https://www.microsoft.com/en-us/learning/exam-70-483.aspx and try to focus on the things
mentioned there.
Best regards,
Leon
