How To Prepare

For guaranteed selection preparation should be well planed, efficient stepwise through best reference books and online test series for csir net PHYSICAL SCIENCE.

Step 1: In first step do not prepare for all the syllabus. Select only few portion of syllabus and general aptitude so that you can only cross the cut off marks. Get the best command in this steps through practice of offline papers, quizzes and online test series.

Step 2: If your preparation is capable to cross the cut off marks then increase one more topic. Always prefer those portion of syllabus in which your command is better. Don’t leave practice of previous topics.

Step 3: After completion of a chapter, check your preparation either offline or through online test series for csir net. Regularly attempt quizzes for specific topics and chapter.

  • What are the features of a good test series.

    Traditionally, five characteristics are listed in statistics textbooks and test construction manuals. Those five characteristics are explained below:

    1) Test Objectivity

    In this case, objectivity refers to the mutual agreement between experts that the test is objective. And that it is free from ambiguity. This also implies that experts agree on items and their scoring. This leads to uniformity and fairness while scoring a test.
    In the case of online tests, test objectivity refers to uniformity in the way items in a questionnaire are presented. And also, that the software is programmed to interpret the test results uniformly.

    2) Test Reliability

    Online testing ensures reliability of tests because during custom construction of assessments, computerized techniques. That are used to ensure that a test consistently produces similar results when administered on the sample (test-taker). 

    Online tests also ensure that there is both internal and temporal consistency in the results derived. Which is very important if we want to make hiring decisions accurately and fairly.

    3) Test Validity

    An important prerequisite of a good test is that it is valid. Test validity is defined as its ability to measure what it intends to measure, when compared with independent. And external factors. Alternatively, we can also define test validity as its quality to correlate positively with certain outside criteria.
    In online assessments, test validity can be ensured by following standard test writing procedures. Test writing is a scientific procedure which ensures that the items of a test are chosen carefully. And tested on a sample, and later standardized on a sample, which helps to provide norms.

    4) Availability of Norms

    An online test has the advantage of being standardized and norms developed very easily. Thanks to its ability to be administered online. It is easier to gain access to samples (people who represent the population or individuals to be studied and assessed) online, and thus, establish norms.

    5) Practicability

    Test practicability is nothing but how practical it is to use it as a test. Practicality comes in terms of the time taken to complete it, its length, scoring and interpretation. It should not take too long. However, it is difficult to define how long is too long.
    A few other characteristics specifically for the online testing environment
    Going further, to adapt tests to an online medium, we have listed five more characteristics of a good online assessment test. 

    These qualities of a test help it to be administered effectively online, without the applicant feeling fatigued or without him/her finding it difficult to respond to question.

    6) Test comprehensiveness

    Online tests are suited for test comprehensiveness because it is easier to factor in all the attributes of a trait that is being measured, and customize the items in such a manner that the administration is practical too, while remaining comprehensive. 

    Usually, practicability of a test is undermined when we make it comprehensive, especially in paper pencil tests. However, in online tests, both practicability and comprehensiveness of the test can be maintained, in order to produce better results.

    7) Time appropriate

    Time appropriateness of a test is slightly different from it being practical. Under practicability of a test, we discussed that it has to be short in duration, with respect to administration, scoring and interpreting. However, time appropriateness of a test refers to its ability to allow for recruitment given whatever the circumstances of a company are.
    For example, one can always deliver a short test that is practical yet comprehensive. But it may not be time appropriate. If the same test is being administered to thousands of job applicants, the entire testing procedure and selection process should be fast too, so that the right candidate is hired without any delays.

    When a test is time appropriate, we can also assume that it is already comprehensive and practical. This is not to say that time appropriate tests are short in nature. 

    On the other hand, they help companies to recruit quickly without testing unnecessary traits. In other words, we test only what is required for that particular job profile, yielding results that which help in making the recruitment decision. Using the internet to administer tests help in remaining time appropriately.

    8) Economical

    Most importantly, a test should not be exorbitantly priced. It should be within the reach of a company’s expenditure for recruitment assessments. Most of the times, buying license to paper-pencil tests cost a lot. This forbids companies from accessing standardized tests that help in making the right hiring decisions.

    Good online tests are not as expensive as paper-pencil tests because, you do not have to purchase license separately for each time you administer it. Usually, the costs are included in custom test construction, which includes professional charges to construct the test plus the software program that administers the tests to applicants.

    What are the factors which decide your the selection for csir net jrf.

    Method of preparation.

    It is the most important factors which decides your selection. It is supposed to be that self study is the best method. But it requires a well planed method. Study of student should not be limited and compressed, it should be research oriented, analytic and explored.

    Go deep into the topic up to limit.

    Be expert in basic concepts.

    Try to go through challenging questions.

    Use and find tricks to solve the problems.

    Be very careful in understanding the questions. Minimize the solving time of questions.
    Previous years cut off trends.

    Previous year cut off is the factor which help to decide the target score for preparation. Average cut off approximately remains stationary with some minor fluctuations.

    Exam analysis.

    The previous year exam analysis tells the following point as-

    There are some definite question pattern from same topic which are regularly repeated. You should be expert of that Not the complete syllabus but only few papers covers marks greater than cut off marks. So in first step you should make yourself expert in that then go ahead

    General aptitude is the most scoring part of the paper. Only a little care will help to score between 25 to 30 marks. Go through regular practice with quizzes and online test series for csir net.

    Number of applicants.

    The Cut Off varies for each exam and each category in a separate manner. Recruitment board decides cut-off based on the toughness of the paper and number of candidates who have attended for that exam. Cut off Marks will be decided based on the Average marks obtained by all the candidates.
