Answer 1

You should simplify this using one checkbox per item.
<div class="checkbox">
<label>
<input type="checkbox" name="Card" value=1>
High School Card (Form 138)
</label>
</div>
Then in php check the results like so....
if(isset($_POST['Card'])){
// Card Completed
}else{
// Card Not Completed
}
