You’re right, the email only mentions 2 hours, MCQs + descriptive. Generally, for Journalism entrance exams, the subjects covered are:

• Current Affairs & General Knowledge (especially related to media/news).
• English Language (grammar, comprehension, essay writing).
• Media & Communication Aptitude (basics of journalism, advertising, public relations).
• Reasoning/Logical Ability (basic aptitude questions).
• Descriptive part usually has essay writing, précis writing, or short answers on media-related topics.

Hope this clear your doubt!
