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 #5 article in this series: Inventors & Inventions.
Often, you will get direct questions on inventors and inventions which can get really confusing. However, there are a few handpicked inventors who feature regularly in entrance tests and so, learning these would dramatically improve your chances of scoring well in such a scenario.
