Displaying multiple tables depending on data available - php

Question

I am trying to display data from multiple tables on one page but I need to do different queries to get all the people to show up. How do I format a query where it will select data from the job/jobSearch table if there is data that matches with the studentID from the student and major tables or select from the education table if there is data that matches the studentID. Both job/jobSearch and the education tables will not have data for the same student at the same time because they will either be choosing that they are employed after graduation or continuing their education so if they choose education they skip the questions regarding employment and vice versa.
<?php
include('includes/db_connect.php');
//include('student.php');
$query_student="SELECT *
FROM student
JOIN major
ON student.studentID=major.studentID
JOIN jobSearch
ON major.studentID=jobSearch.studentID
JOIN job
ON jobSearch.studentID=job.studentID
JOIN education
ON job.studentID=education.studentId";
$result_student=mysqli_query($conn, $query_student) or die(mysqli_error($conn));
echo '<table>
<tr>
<th>First Name</th>
<th>Last Name</th>
<th>Graduate Year</th>
<th>Major</th>
<th>Activity After Graduation</th>
</tr>';
while($row = mysqli_fetch_array($result_student))
{
echo'<tr>'; // printing table row
echo '<td>' . $row['firstName'] . '</td>';
echo '<td>' . $row['lastName'] . '</td>';
echo '<td>' . $row['gradDate'] . '</td>';
echo '<td>' . $row['major'] . '</td>';
echo '<td>' . $row['activity'] . '</td>';
echo'</tr>'; // closing table row
}
echo '</table>';
$conn->close();
?>
