Please let us know what we can do to make this system better.
Install instructions follow.

A full featured simple grader report requires the simple tree, anonymous grade block, a slight modification to the existing theme's header.html, and a slight modification to lib/grade/grade_item.php.

• Once the simple grader has been installed, editing the header.html should consist of adding the following lines in the 'head' element:

<?php $filenamejs = "$CFG->dirroot/grade/report/simple_grader/lib/menufixer.php";
if (file_exists($filenamejs))

{ include($filenamejs); }

?>

• The modification in grade_item.php is simply changing:

var $aggregationcoef = 0;

to:

var $aggregationcoef = 1;

• Add a check for Simple Grader report to gradelib, located in {MOODLE_ROOT}/lib/gradelib.php:
  
  At the very beginning of the function grade_regrade_final_grade, you must add code that calculates core modules correctly. So, the code below must be added right under the function declaration line which looks something like:
  
  function grade_regrade_final_grades($courseid, $userid=null, $updated_item=null) {
  // Check for Simple Grader Report
  global $CFG;
  
  $exists = file_exists($CFG->dirroot. '/grade/report/simple_grader/lib/simple_gradelib.php');
  if ($exists) { require_once($CFG->dirroot . '/grade/report/simple_grader/lib/simple_gradelib.php'); return simple_grade_regrade_final_grades($courseid, $userid, $updated_item); }
  
  * Add a similar check in {MOODLE_ROOT}

  /grade/import/lib.php around line 55 in function grade_import_commit add the following:

$use_function = false;
$file = $CFG->dirroot . '/grade/report/simple_grader/lib/simple_gradelib.php';
if (file_exists($file))

{ require_once($file); $use_function = true; }

Then jump to around line 82:

....
// insert each individual grade to this new grade item
foreach ($grades as $grade) {
if ($use_function){
if(!simple_update_final_grade($grade->userid, $gradeitem, 2, $grade->finalgrade, 'import', $grade->feedback, FORMAT_MOODLE))

{ $failed = true; break 2; }

} else if (!$gradeitem->update_final_grade($grade->userid, $grade->finalgrade, 'import', $grade->feedback, FORMAT_MOODLE))

{ $failed = true; break 2; }

}

And lastly around line 125:

....
// make the grades array for update_grade
foreach ($grades as $grade) {
if (!$importfeedback)

{ $grade->feedback = false; // ignore it }

if ($use_function){
if(!simple_update_final_grade($grade->userid, $gradeitem, 2, $grade->finalgrade, 'import', $grade->feedback))

{ $failed = true; break 2; }

} else if (!$gradeitem->update_final_grade($grade->userid, $grade->finalgrade, 'import', $grade->feedback))

{ $failed = 1; break 2; }

}

• Denying access to the original grader report. Fortunately, this can be done in Moodle, defining capabilities.

With the Site Administration block navigate to Users->Permissions->Define Roles. For every role, change the gradereport/grader:view to "Not Set"

This will deny access to the original gradebook.

Note: in order to get help files to make sense in the simple tree, make sure that the help files location in simple_tree/lang/en_utf8/help/grade/ are moved into core.
