SNAP 2015 GK Preparation
SNAP 2015 GK Preparation series. GK is a differentiator when it comes to SNAP. Most of the aspirants don’t prepare for the section and end up scoring below expectations. Though one cannot prepare for GK in a month, one can always do things that are enough to do reasonably well in the test. One can prepare topic wise, go through past papers and find the commonly asked GK topics and even take calculated guesses in the test. To help you prepare for SNAP 2015 GK section, we are going to write a series of articles focusing on GK. Every article will also be available in PDF format for download and easy viewing. Let’s dive into our #4 article in this series: Instruments & Uses.
Over the last few years, instruments and their uses have consistently appeared in the GK section of the various entrance tests. Here is a short list of the commonly used instruments with their usage. Aspirants are advised to read through the entire list as the knowledge would also be useful while handling other questions as well, due to the common word roots.
