Math Tricks for Sainik School Aspirants

For many students preparing for the Sainik School entrance exam, mathematics is the most important subject, as it has the most weightage. Even well prepared student sometimes lose marks not because they do not know the concept, but because they take too much time or make small calculation mistakes. In competitive exams like AISSEE, RMS and RIMC, Speed and accuracy matter just as much as knowledge.

That is why smart math tricks play a very important role for Sainik School aspirants. Tricks do not replace concepts. Instead, they help students apply concepts faster and with more confidence during the exam.

In this blog, we will discuss some easy math tricks that every Sainik school aspirant should know, and how the right guidance can help students master them.

Fast Squaring Techniques

Questions involving squares are common in Sainik school exams. Especially for classes 6 and 9. Students who calculate squares using long multiplication waste valuable time.

For example, squaring numbers ending with 5 is very easy if the student knows the trick.

252 can be solved as 2x3=6 and add 25 in the last, so the answer is 625.

352 can be solved as 3x4=12 and add 25 in the last, so the answer is 1225.

With regular practice, students can solve such questions in seconds without pen and paper.

Percentage Conversion Shortcuts

Percentage-based questions often look lengthy, but they can be solved quickly with the right approach. For example, 25% is the same as one fourth, 50% is one half, and 20% is one fifth. Instead of calculating 25% of 200 by multiplying and dividing, students can simply do 200 divided by 4, which gives 50. This saves time and reduces the chances of error.

At Lakshya Academy, students are trained to recognise these patterns instantly so that they do not panic during the exam.

Time and Work Smart Methods

Time and work questions can be confusing if solved using traditional methods. However, using the unit method makes them very simple.

If one student can complete a task in 10 days, then their one day's work is one-tenth. If another student completes the same task in 5 days, their one day's work is one-fifth. Adding work becomes easy using fractions.

This method helps aspirants solve even complex questions with clarity and confidence.

Simplification and BODMAS Awareness

Many students lose marks in simplification questions because they ignore the correct order of operations. Remembering BODMAS is essential, but applying it quickly is equally important.

Practising mental calculation and breaking expressions into smaller parts helps students avoid silly mistakes. Regular timed practice builds discipline and accuracy.

At Lakshya Academy, special drill sessions are conducted where students solve such questions under exam-like conditions.

Knowing math tricks is one thing, but applying them correctly in an exam is another. At Lakshya Academy, students are not just taught formulas. They are trained to think like exam toppers.

Each topic is covered with concept clarity first, followed by shortcut techniques, exam-focused questions, and timed practice. Teachers closely monitor student progress and correct mistakes early, before they become habits.

Lakshya Academy also focuses on building confidence. When students know they can solve questions quickly, their fear of mathematics disappears. This confidence reflects in their overall exam performance.

Parents trust Lakshya Academy because of its disciplined environment, experienced faculty, and result-oriented teaching approach designed specifically for Sainik School, Military School and RIMC entrance exam aspirants.
