OMR Variant
+
+
Creating variants:
+
+
+
Generating Variant Numbers:
+
+
Click on the OMR tab and then variants tab.
+
If not created already, based on the OMR configuration parameter "variantcount" that many number of variants will be created automatically with empty "variantnumber" 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.
+
+
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
+
+
+
+
+
Deciding Question Sequence for each variant:
+ There are three options for deciding question sequence for a variant.
+
+
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.
+
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.
+
+
+
Manual Shuffle: For shuffling questions manually click on the “manual shuffle” button. Use up and down arrows to move a question up and down.
+
+
+
+
+
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.
+
+
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.
+
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.
+
+
+
+
Printing Variants:
+
If variants are already created then the variants can be viewed and printed.
+
+
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.
+
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.
+
Click on your web browser's print button to get a hard copy of the quiz paper.

Creating and Uploading the OMR Configuration File
+
+
Creating OMR Configuration File
+
+ The configuration file contains certain parameters that helps in flexible extraction of offline attempt data from the scanned omr answer sheet data file.
+
+ For structure and contents of configuration file refer to "Structure of configuration file" and "Contents of the configuration file".
+
+ Configuration file can be created once you have scanned OMR answer data file. Based on that file various parameters of configuration file are decided.
+
+
+
1. Structure of Configuration File:
+
name_of_the_parameter:value_of_the_parameter
+
+
2. Contents of the Configuration File:
+ Following are the contents of the configuration file(order does not matter):
+
+
Parameter
Value required
+
+
+
rollnoposition
+
Position of roll number in scanned OMR File.
+
+
+
rollnolength
+
Length of the Roll number
+
+
+
ansposition
+
Position of the answer string in scanned OMR File
+
+
+
variantposition
+
Position of the Variant number in scanned OMR File
+Note: configuration file should be a simple text file. Any other complex format such as MS Word etc
+will not work.
+
+
+
Uploading OMR Configuration File:
+
+
+
Click on the OMR tab. System will ask for OMR configuration upload if the configuration file is
+not already uploaded.
+
+
Click on “browse” under “import from file upload” section and click “upload this file” to upload the
+configuration file present on your file system.
+ OR
+Click on “choose or upload a file” under “import from file already in course files..” section and click
+“import from this file” to import the configuration file that is already present in files area of Moodle.
+
+
If you are re uploading the OMR configuration file involving a change in the parameter
+“variantcount” then a warning will be shown that:
+
+
+“if you change the OMR configuration then all the existing answer data and user attempts made on
+that data for this OMR quiz will be erased”.
+Click “yes” if you intend to do so. Click “no” otherwise.
+After the file upload, contents of the file are displayed on the screen.
+Click on the “continue” button to decide the variants of quiz.

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