The JET BCA exam checks what you know in a few key areas. You'll have to read and understand passages in the Reading Comprehension part. For Basic Mathematics, expect questions from your 12th-grade math, like simple algebra and arithmetic problems involving averages and percentages. Logical Reasoning will test your brain with puzzles, identifying patterns, and understanding relationships. There's also a section on General Knowledge and Current Affairs to see how aware you are of what's happening around the world. Sometimes, there might be a few basic computer-related questions too.

The exam is usually online, and you'll answer multiple-choice questions. You'll likely have around two hours to complete it. A good thing to know is that generally, there's no penalty for wrong answers, so it's usually best to attempt every question. To do well, focus on practicing these different areas and staying updated on current events.
