Dear,

The most important rule while preparing for the exam is to know the syllabus and pattern thoroughly. Knowing the AP PGECET 2020 syllabus will enable you to ensure that you are aware of all the topics that must be covered during the preparation process. I would recommend following William Mooty and G.K Publications for your preparation. I would suggest not to miss any topic from the syllabus. Solve as many papers as you can to get hold over the questions.

You can find the entire syllabus for CSE course with past year question papers on the following site:

Hope this helps!
