Uploading and Correcting the Answer Sheet Data:

Structure and Contents of scanned OMR answer sheet data file:

+
  1. Structure of the scanned OMR answers file
    + +OMR sheets can be scanned to obtain the student attempt data (consisting of student information & answers) in digital format. Currently OMR quiz requires the offline quiz attempt data in a standard format. +
    +

    Following are the details of the format:
    +     Each line should consist of a single student record only

    + + +

    +Note: + Scanned data format for OMR sheets differs from scanner to scanner and OMR sheet to OMR sheet. So, if scanned data is not available in above mentioned format, you can preprocess the scanned student quiz attempt data to obtain data in above mentioned format & smoothly do the result processing using OMR Quiz. In this way, you can potentially process student offline attempt data conducted on any OMR sheet irrespective of the scanner which was used for scanning the sheets or the structure of the OMR sheet. +

    Analysis and Correcting the Answer Sheet Data:

    + + +Content: + + + + +

    Analysis of uploaded OMR answer sheet data:

    +

    Answer data analysis is done for detecting problems with the uploaded records. There are two types of analysis available for uploaded answer data.

    +
    1. Record wise analysis:
            When you upload the answer data then the system automatically performs the analysis and shows it record by record. If answers were already uploaded then just click the “upload answers” tab to see the record wise analysis of answer data.

      2. +
    2. Error category wise analysis:
           Under the “upload answers” tab click on the “diagnostics:” list and choose “category wise” and click on “show” button.
    +

    Diagnostics will be shown based on error category.

    +[TOP] + + + +

    Corrective actions on answer data:

    +

    After detecting the problems with the uploaded data you can go and manually change a copy of Scanned OMR data file.

    +

    After seeing the diagnostics the user should manually change the problematic records in the scanned answers file and re upload that file to system.

    +

    For re uploading an answer file go to “upload answers” tab and click on the “change” button present at the bottom of the page and follow the procedure as described in “Upload answers” section above.

    +

    NOTE: Do not change original scanned OMR data file. Always make a copy of it and do the changes on that file.

    OMR Variant

    + +

    Creating Variants:

    + +
      +
    1. Generating Variant Numbers:

      +
        +
      1. Click on the "OMR" tab and then "Variants" tab.

        2. +
      2. If not created already, based on the "OMR" configuration parameter "variantcount" that many number of variants will be created automatically with empty "Variant No" field and a default question sequence in "Question Sequence" field. This is the sequence of the questions as present in the master quiz. +
        Note: in the question sequence field each question is represented by its unique id. +

        3. +
      3. Enter the desired variant number for each of the Variants, if not done already and click on "save changes" button.
        + Note: Variant numbers are unique for a quiz.

        4. +
      +

      2. + + +
    2. Deciding Question Sequence for each Variant :
      + There are three options for deciding question sequence for a variant :

      +
        +
      1. Change sequence directly from the text area by placing the question ids at desired place. The sequence should be comma separated with a 0 at the end of the sequence.
        Note: "0" denotes Page Break.

        2. +
      2. Automatic Shuffle: For shuffling the question sequence click on the “shuffle” button.
        + Click on the “save changes” button to save the changes made by shuffling the questions. +

        3. + +
      3. Manual Shuffle: For shuffling questions manually click on the “manual shuffle” button. Use up and down arrows to move a question up and down.

        4. +
      +

      3. + + +
    3. Adding page breaks:
           A page break after a question means the next question will appear on a new page. Page breaks can be added in the question sequence by two ways :

      +
        +
      1. Page break in "question sequence" text area: Add a "0" in the "Question Sequence" text area at the desired place and click on "save changes" button.

        2. +
      2. Page break using "Manual Shuffle" :
        click on "manual shuffle" button then click on "show page breaks" and use up arrow present against last page break to introduce a new page break. Then place it at the desired place using up and down arrows.

        3. +
      +
      4. +
    +

    Printing Variants:

    +
    1. If Variants are already created then the variants can be viewed and printed :
      2. + +
      1. Click on "preview" link present against the variant that you wish to preview. A printable version of the variant will be presented on the screen.

        2. +
      2. Now click on your browser's print preview option to see the layout of the questions along with page breaks. You can go back and adjust the question sequence or page break position if layout is not proper.

        3. +
      3. Click on your web browser's print button to get a hard copy of the quiz paper.
