The IIMB Test is a computer-based, proctored exam lasting 120 minutes—plenty of time to showcase your skills, but tight enough to demand precision. It's structured around 60 multiple-choice questions (MCQs), divided into three sections that test the holistic competencies needed for data science and economics. Unlike sprawling entrance exams, this one's laser-focused, emphasizing speed, accuracy, and conceptual depth over rote learning.
The IIMB Test: Exam Pattern at a Glance
| Section | No. of Questions | Focus Areas | Time Allocation Tip |
| English Comprehension | 15 | Reading passages, grammar, vocabulary, verbal reasoning, semantic interpretation | 25-30 minutes; prioritize quick scans for inferences. |
| Quantitative & Data Interpretation | 30 | Arithmetic, algebra, geometry, statistics, probability, data visualization, economic modeling basics | 50-60 minutes; the heavyweight—tackle easy quant first. |
| Logical Reasoning | 15 | Puzzles, sequences, syllogisms, analytical deduction, critical thinking | 25-30 minutes; spot patterns swiftly to avoid traps. |
Total: 60 questions, 120 minutes—about 2 minutes per question on average. The quantitative section dominates with 50% weightage, reflecting the programs' data-centric core. Questions draw from Class 12 syllabus but twist into application-based scenarios, like interpreting economic datasets or logical flows in business cases. No sectional time limits mean flexibility, but poor time management can sink you. Testfunda's mocks simulate this exactly, with adaptive difficulty to mimic the real pressure.
Syllabus-wise, expect Class 12-level math (calculus, matrices, probability) fused with data interp (graphs, tables, caselets). Verbal draws from standard comprehension, while LR tests puzzle-solving under constraints. General knowledge isn't explicit, but current affairs might weave into passages. Official sample papers, released by October 2025 on iimb.ac.in, are gold—practice them religiously.
