#### Trouble joining 3 different tables in Laravel

I am using Laravel 7 and am trying to join 3 tables and for the most part, it is working great. The problem is that my table is returning the first test result it sees which is 33% and repeating it for all the other rows. I am new to joining in Laravel and need some assistance.
Here are my tables
oex_students

oex_results table

and finally the oex_exam_masters table

In the dashboard, I am calling the join in the index function within the AdminController.php

public function index()
{
$data['portal'] = Oex_portal::get()->toArray();$data['exams'] = Oex_exam_master::where('status', '1')->get()->toArray();
$data['result_info'] = Oex_result::select('oex_results.*', 'oex_results.result as result')->get()->first();$data['students'] = Oex_students::select(['oex_students.*', 'oex_exam_masters.title as exam_name'])
->join('oex_results', 'oex_students.id', '=', 'oex_results.user_id')
->join('oex_exam_masters', 'oex_results.exam_id', '=', 'oex_exam_masters.id')
->get()
->toArray();

$data['category'] = Oex_category::where('status', '1')->get()->toArray();$data['exams'] = Oex_exam_master::select(['oex_exam_masters.*', 'oex_categories.name as cat_name'])->join('oex_categories', 'oex_exam_masters.category', '=', 'oex_categories.id')->get()->toArray();
return view('admin.dashboard', $data); }  In my dashboard where I am displaying the table is:  @foreach($students as $key =>$student)
<tr>
<td>{{ $key+1 }}</td> <td>{{$student['name'] }}</td>
<td>{{ $student['email'] }}</td> <td>{{$student['mobile_no'] }}</td>
<td>{{ $student['exam_name'] }}</td> {{-- <td>{{$student['result'] }}%</td> --}}
<td>{{ $result_info->result }} %</td> {{-- <td>N/A</td> --}} @if($student['status']== 1)
<td><input data-id="{{ $student['id'] }}" class="student_status" type="checkbox" name="status" checked></td> @else <td><input data-id="{{$student['id'] }}" class="student_status" type="checkbox" name="status"></td>
@endif

</tr>
@endforeach


Here is an image where the information is displayed:

I want to call the result where the oex_students.id = oex_results.user_id but I am not sure how to go about this using Laravel. Thank you very much in advance for your help.
