About the MAT Test
What does mental ability mean for a Class 8 student?
Once the students reach Class 8, mental ability tests look different from the ones they faced in Class 6 or 7. The questions are longer, the logic chains are deeper, and problems like blood relations or train-speed puzzles suddenly appear that are hard to crack. This requires students to hold multiple pieces of information in their heads at the same time. It is less about quick pattern spotting and more about structured thinking.
This matters because Class 8 is also the year many students start preparing seriously for NTSE. NTSE has a dedicated Mental Ability Test (MAT) paper of 100 questions. The habits you build now, like –
- Reading questions carefully
- Eliminating wrong options
- Checking your logic
Are directly going to transfer to the exams.
What types of questions are in this set?
The 80 questions below are spread across 8 categories that cover the full range of topics tested in Class 8 reasoning exams. Analogy questions test students to identify relationships between pairs of words or concepts. These appear consistently in both NTSE and most school-level Olympiads. Coding-decoding questions involve letter and number substitution patterns. This sounds simple, but it might create issues for many students who rush it. The puzzle section includes some classic lateral thinking problems. A few of the questions in these categories are genuinely hard, and that is intentional.
The sequence questions in the list below go beyond simple doubling or addition. Some involve square numbers, alternating operations, and a couple use Fibonacci-type logic. The blood relation section is where Class 8 students might lose the most marks in actual exams. The multi-step chains look straightforward but have subtle traps, particularly when gender is left unspecified.
Analytical and numerical reasoning questions toward the end involve ratios, speed-distance, algebra, and geometry. These are not pure maths. They are reasoning questions in a mathematical format. This distinction matters when you are solving them.
A note before you start
A few questions in the coding-decoding and sequence sections have patterns that look similar but work differently. If you are preparing for NTSE or an Olympiad, try to solve the questions while keeping time in mind. 90 seconds per question might be good for real exam conditions. If you are using this for general practice, do not rush. Focus on the reasoning, not the speed.

Frequently Asked Questions
How is Class 8 MAT different from Class 6 or 7?
The core questions are more or less the same, analogies, sequences, coding, and classification. However, the difficulty level shifts a bit. Class 8 questions involve more steps, more conditions, and less obvious answers. Blood relation problems in Class 8 have 4-5 steps instead of two. Numerical reasoning questions are algebra and ratio-based. The biggest difference is that you might now have to rely on intuition alone. You have to work through the logic systematically.
Are these questions relevant for NTSE preparation?
Yes, directly. The NTSE MAT paper covers exactly the categories in this set: analogy, series, coding-decoding, classification, blood relations, and analytical reasoning. The difficulty level of the set is slightly easier than that of the actual NTSE questions. That makes this a good starting point. Once these feel comfortable, move to the previous year NTSE MAT papers for the final step up in difficulty.
My child is getting answers right but failing in timed tests. Why?
This is one of the most common problems at this level. The reason might be that the student is solving correctly but slowly. This means they understand the concept but haven’t automated the process yet. Timed practice will fix that. Another reason might be that they are using a longer method than necessary. For example, in sequence questions, students who test each option individually take far longer than students who identify the rule first. Look at how your child is solving the problems. If required, ask what steps they have taken to solve the questions.
Which topics should a Class 8 student focus on most?
Blood relations and analytical reasoning deserve the most practice time. They are high-weightage and have a steep learning curve. Series and analogy questions are a bit easier because the patterns are more predictable once you’ve seen a lot of them. Coding-decoding sits in the middle. The concept is simple, but the variations are numerous. Practice matters more than volume when mastering the MAT test.
Are 80 questions enough to prepare for a Class 8 reasoning exam?
For a first round of practice, yes. The goal of this worksheet is familiarity. We have tried selecting questions to help students become comfortable with each question type. After solving these questions, students will not be surprised in a real test. After this, students have to work through at least two or three different question banks and past papers. Eighty questions done thoughtfully will take you further than three hundred done mechanically.
Can these questions be used for class tests or school assignments?
Teachers use these regularly for unit tests, remedial sessions, and enrichment work for students who finish early. The questions are grouped by category, so it is easy to pull a section. Each section can be used as a 15-minute class activity. The answer explanations make self-correction straightforward, which also reduces the marking burden.
