Which chapter should I start with?

With percentage, because profit and loss, interest and many mixed problems all stand on it.

How do I calculate fast without a calculator?

Memorise tables, squares and cubes, and learn to work with approximations. Most of the arithmetic then happens in your head.

Mathematics Preparation for Job Exams

Q: What if a problem sticks?

Leave it and move on. Getting stuck on one hard problem and losing three easy ones is the costliest mistake in this exam.

The number of mathematics chapters in job exams is surprisingly small while the volume of questions is large. That means the real task is not learning something new but getting fast in familiar chapters.

The chapters that recur

Chapter	Where it is used
Percentage	The base for profit, loss and interest
Ratio and proportion	Division and mixture problems
Average	Both direct and indirect forms
Time and work	Through the idea of unit work
Time and distance	Train and boat problems
Simple and compound interest	Regular in bank exams
Area and mensuration	Applied geometry

Practical routes to speed

Know tables, squares and cubes up to twenty.
Memorise the common fractional forms of percentages.
Learn to verify by substituting the options.
Work with approximations, then confirm.

If the foundation is weak

Many find job-exam mathematics hard when the problem is not the chapters but the foundation. If the basic arithmetic of fractions, decimals and percentages is shaky, every chapter above it feels difficult. Going back a few weeks to the class 8 mathematics text is nothing to be ashamed of — it is in fact the fastest route.

Managing time in the hall

In the hall you do not need to solve every problem; you need to get the most problems right. If one has not opened in thirty seconds, leave it and come back if time remains. Getting stuck on one hard problem and losing three easy ones is the most expensive mistake in this paper.
