Objective Solving Tricks for GATE exam
Most of time students complain that they couldn’t complete their objective paper; they were struck in one or another problem and wasted a lot of time. Some says that their guess went wrong and marks were deducted due to negative marking, some could not read paper completely and missed some easy questions etc.
I’ll like to stress that objective paper solving is different from subjective paper. You don’t need to study extra for objective questions but practice little bit.
Your guess in solving objective can bring you in difficulty but some intelligent/educated guess can add valuable marks to your score. Most of time objective questions havesome hint in the form of multiple choices for the question.
Following can be used as guidelines for solving objective paper:
General Tips
Keep the structure of GATE in mind(25 Quest 1 Mark each, 30 Quest. 2 Marks each with 4 common data questions and 4 Linked Questions).
Plan your time. Allow more time for high point value questions; reserve time at the end to review your work, and for emergencies. I'll suggest following sequence, but you can keep as per your choice: 2 Marks question, Common Data Questions, Linked questions and then single mark questions.
Look the whole test over, skimming the quesitons and developing a general plan for your work. If any immediate thoughts come to you, jot them down in the margin
Start with the section of the test that will yield the most points, but begin working with the easiest questions to gain time for the more difficult ones and to warm up.
Work quickly, check your timing regularly, and adjust your speed when necessary.
Avoid reading into the questions. When you find yourself thinking along the lines of "this is too easy; there must be a trick..." mark the question and move on to another. Interpret questions literally.
Mark key words in every question. To help find the key words, ask yourself WHAT, WHO, WHERE, WHEN, and HOW?
Multiple Choice Specific Tips
Remember in GATE each question will have four choices for the answer, only one is correct and wrong answer carry 33% negative marks
Read the question (without reading choices) very carefully.
Mark important key words and look for special key words like not, but, except , or, nor, always, never, and only . Mark these key words. E.g.
Ques The number of leaf nodes in a rooted tree of n(n>0) nodes, with each node having 0 or 3 children is:
Important words to mark in this are, "n>0" and "or"
The number of leaf nodes in a rooted tree of n(n>0) nodes, with each node having 0 or 3 children is:
Many times we miss words like "or" and whole question in changed.
If you can think of answer before reading choices, keep it in mind before reading choices
Compare with choices and select the best suited answer.
Most of times choices are made to confuse. If there are two or more options that could be the correct answer, compare them to each other to determine the differences between them.
If there is an encompassing answer choice, for example "all of the above", and you are unable to determine that there are at least two correct choices, select the encompassing choice.
Make educated/intelligent guesses - eliminate options any way you can.
Multiple choices can provide direct short cut to get correct answer, especially in numerical problems. For example in the above question
Example
The number of leaf nodes in a rooted tree of n(n>0) nodes, with each node having 0 or 3 children is:
Choices:
A n/2
B (n-1)/3
C (n-1)/2
D (2n+1)/3
Direct solving the problem can be difficult. Use following short cut.
Imagine few such trees and try to get answer from choices. Lets start with tree with one node, i.e. n = 1. In this case obviously number of leaves should be one(same as root). Putting n=1 in above options only option "D" gives 1. But assure your self with more tries. Next possible value of n = 4 with number of leaves = 3. Putting this is multiple choices only "D" satisfies confirming our solution.
