    /* echo "cat : ".$cat = $k2[0] ."-". $v;
    echo "<br>";
    echo "Que : ".$que = $k2[1]."-". $v;

Just update your loop like as

$cat_array = array();
foreach($assesment as $k => $v){
    $k2 = explode("_",$k);
    if(isset($cat_array[$k2[0]])){
        $cat_array[$k2[0]] += $v;
    }else{
        $cat_array[$k2[0]] = $v;
    }
}
