Multiple Choice Questions Answering Techniques

Now a days, most of the Competitive Exams, Entrance Exams are conducted on MCQ method.
So, it is essential to perform well at MCQ, irrespective of how good you learn.
If you are preparing for MCQ type of test, then your study and exercise plan would be somewhat different from Regular Tests in which you have to write full answers in paper in the exam.
In some cases, you have to tick the correct answer with Pencil in Question paper itself (Pencil & Paper Test). In some case, you have to select the right answer on a digital device like Phone, Computer, Tablet, etc (On-line Test). However, the concept of writing answer remains same, in both cases.
For MCQ Test, first study Books, Blogs, Video / Audio tutorials to understand the concept. Immediately, after studying a chapter, attempt answering MCQ. It is not good idea to study and answer MCQ after a long gap. You must attempt MCQ immediately after studying the topic. By attempting MCQ, you will understand the strength and weakness of your leaning process and assess yourself regularly, MCQ is very effective self assessment process.
The opening of each MCQ starts asking a question, a problem to be solved, or an incomplete statement to be completed (stem of the Question). The Question (the Stem) is followed by set of Options (normally 4 or 5). Only one option is correct (called the key) and other options are wrong (called distractors). Respondent are asked to mark the key (the correct option).
The aim of the test is to assess the analytical and problem-solving approach of the examinee, rather that cramming. So, similar looking options are set in the MCQ to confuse a bit, driving the examinee to think analytically. The examinee with clear understanding and problem-solving approach, would be able to identify the key from distractors.

How to Answer MCQ

MCQ tests are tightly time constrained. So, do not waste long time over a question. If not sure, skip it, and come back later on. However, in Tests, it is not possible to come back to a question. Each question must be decided instantly.
First read the question (the stem), carefully. Understand the intent of the Question. Sometimes a problem is asked, sometime a gap is to be filled up. Sometime, the question asks to select wrong answer (native Question). In such case, the wrong statement is the correct answer (wrong is right! Or right is wrong!). Such negative questions are deceptive to confuse the examinee. Be very careful, in negative questions.
Often, the longer options is correct (but not always as rule !). Because the examiner wants to make sure that the right is right option is clear. So, re-read long options. Sometimes, the options closely resemble. Some options are not totally wrong, but one options is clearly closest to the intent of the question. That is the correct option. It is a bit difficult to identify correct option in such case.
Shed your fears! Be confident.
