Pa help po ayaw po kasi gumana nung session gusto ko sana yung score nag iincrement pag tumama yung sagot nya sa radio button
then pag na change ung page yun pa rin yung score nya once na hindi nag sasagot then increment ulit.. I hope na matulungan nyu ko..

Sainyo nalang ako umaasa kasi mga kaklase ko di ako tinutulungan halos thesis namin ako lang gumagawa

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;
