There are many a times when new topics are incorporated or additional questions are added (wherever required in that particular section or topic) as per the Academic & Market requirements based as per the discretion of the Mentors and Experts at CloudX Lab.
These questions are framed in such a manner so that students are able to crack their respective interviews at the end of their training schedule.
I as a student too have experienced numerous additions to the syllabus especially in Python and related topics.
Thus, in brief, you need to re-revise the submitted questions for that particular topic and cross-verify whether you have missed out any.
Hope this helps!!!
