is there a way to get the value from a input before the form – PHP

Ok I am editing my answer following code should give you the results, notice I moved the code that was calculating score to place httml output is starting.

This code handle your errors too

<?php
$ans = array();
$GLOBALS['score'] = 0;
$answer = array("Greenland", "Sun", "H2O", "Diamond", "-4a + 22b", "Debugging", "Consummatum est", "he'd", "Douglas macarthur", "x2 + x - 20"); 
extract($_POST);
$questions= array(
            array("What is the biggest Island in the world","Greenland", "Hawaii", "Porto Rico"), //Greenland
            array("Nearest star to earth", "Sirius", "Sun", "Alcyone"), //Sun
            array("Chemical formula for water is", "NaAlO2", "H2O", "CaSiO3"), //H2O
            array("The hardest substance available on earth is", "Vibranium", "Adamantium", "Diamond"), //Diamond
            array("Combine terms: 12a + 26b -4b – 16a.", "4a + 22b", "-28a + 30b", "-4a + 22b"), //-4a + 22b
            array("The process of finding errors and fixing them within a program.", "Fixing", "Finding", "Debugging"), //Debugging
            array("Dr. Jose Rizal's last words", "Farewell my friend", "See you in the other side", "Consummatum est"), //Consummatum est
            array("He said that ________ love me", "he'd", "he would", "he woulded"), //he'd
            array("Who said the line I SHALL RETURN", "Jesus Christ", "Sir Arni", "Douglas macarthur"), //Douglas macarthur
            array("Multiply: (x – 4)(x + 5)", "x2 + x - 20", "x(x + 5) -4(x + 5)", "7")); //x2 + x - 20 

if(isset($_SERVER['REQUEST_METHOD']) && $_SERVER['REQUEST_METHOD'] === 'POST'){
    //$ans = array($_POST["option1"], $_POST["option2"],$_POST["option3"],$_POST["option4"],$_POST["option5"],$_POST["option6"],$_POST["option7"],$_POST["option8"],$_POST["option9"],$_POST["option10"]); // user answer
    
    //echo '<pre>'.print_r($_POST,true).'</pre>';
    foreach($_POST as $key=>$value){
        if(substr($key,0,6) === 'option'){
            $ans[] = $value;    
        }
    }
    //echo '<pre>'.print_r($ans,true).'</pre>';
    $result = array_intersect($answer, $ans); //correct answers
    $name = $_POST['name'];
    $score = count($result); //score
}
echo "<table>";
echo "<tr>";
echo "<td style="border-top: 14px solid #7349BD;"><h3>Answer the Following:</h3>";
//show score here
    if(isset($submit))
    {
    echo "<h2>Congratulation $name, Your score is ";
    echo $score;
    echo "/10</h2>";

    }
echo "<form action="LabAct2_2.php" method="post">";
    $counter=0;
    echo "<hr><label>Name: </label><input type="text" name="name" required>";
    echo "<p>*Required</p>";
    echo "</td></tr>";
    foreach($questions as $value){
        $counter++;
        echo "<tr>";
        echo "<td>";
        foreach($value as $v=>$item)
        {
            if ($v==0)
            {
                echo "<label>$counter. $item</label><br>";
            }else{
                echo "<input type="radio" name="option$counter" value="$item" id="$item"><label for="$item">$item</label><br>";
            }
        }
    echo "</td>";
    echo "</tr>";
}
//error_reporting(0);
echo "</table>";
echo "<div>";
echo "<input type="hidden" value="$score" name="point">";
echo "<input type="submit" name="submit" value=Submit></form><br>";


if(isset($submit)){
    echo "<h2>Congratulation $name, Your score is ";
    echo $score;
    echo "/10</h2></div>";
}
