A one-page table of the forty most-asked section numbers across the IT Act, the BSA, the BNS and BNSS and the DPDP Act, the six leading cases in one line each, and a 25-question practice set covering the whole Cyber Law syllabus.

  4. Practice set: 25 questions
Cases checked to exist. Read the judgment before quoting a holding.

Every case cited here has been checked to exist — the citation resolves and names the right parties. The propositions attributed to each case have not been verified line by line against the judgment. Case names link through to the full judgment: read it before quoting a holding in an examination answer, and never carry a proposition from notes into court on trust.

Cyber Law is about two AIBE questions, and nearly every one is a section number or a case. Mark the sections in this table in your bare acts before the exam. Then attempt the 25 questions below without looking, and check each answer.

How AIBE asks this

Most Cyber Law questions in AIBE give a description and ask for the section, or give a case and ask for its holding. Some test the change from the old laws to the new (section 65B to section 63 BSA) or a number in the rules (fifty lakh users, six hours, sixty days). Practise matching in both directions: section to content and content to section.
