Pa help po ayaw po kasi gumana nung session gusto ko sana yung score nag iincrement pag tumama yung sagot nya sa radio button

Hi sir, I advise you put your code somewhere online so that we can simulate it and find the errors:

But based on visual inspection. you should store Session of score. On line 44 of your code add in the next line:

$_SESSION["score"] = VALUE_OF_THE_SCORE_HERE;
or
$_SESSION["score"] = $score;

To retrieve the score in session:

what_is_the_current_score = $_SESSION["score"];

Also, in line 7, every restart of the page the score will always set the score to zero. So instead setting it to zero. Do a check if $_SESSION['score'] exist:

if (isset($_SESSION['score'])){
    score = $_SESSION["score"];
}
else {
    score =0;
}

Don't forget to set $_SESSION["score"] = 0; after the test is done

Wag mo kasi palitan session name

Value lang palaitan mo

Bale

$_SESSION['score'] = 0;

Yan sa una

Pag mag increment ka ganto

$prevscore = $_SESSION['score'];
$newScore = $prevscore + 1;
$_SESSION['score'] = $newScore;
