Asking an advise about Pivot Table - laravel

Question

I have 3 tables like this
Student:
id | name
class Student extends Model
{
protected $table = 'students';
public function marks () {
return $this->belongsToMany( 'App\Models\Subject', 'marks' )->using( 'App\Models\Mark');
}
}
Subject:
id | name
class Subject extends Model
{
protected $table = 'subjects';
public function marks () {
return $this->belongsToMany( 'App\Models\Student', 'marks' )->using( 'App\Models\Mark');
}
}
Mark:
subject_id | student_id | type_of_exam | times_taking_exam | mark
class Mark extends Pivot
{
protected $table = 'marks';
public function student() {
return $this->belongsTo('App\Models\Student','student_id');
}
public function subject() {
return $this->belongsTo('App\Models\Student','subject_id');
}
public $timestamps = false;
}
The table Mark which has 4 column primary key (id_subject, id_student, type_of_exam, times_taking_exam)
I don't know my design database is correct or not, but if it did, how can I use sync to update or insert mark for my student.
Because I understand that the method sync is like this:
$student->marks()->sync([
$subject_id => [
'type_of_exam' => 1,
'times_taking_exam' => 1,
'mark' => 10,
]
]);
But it is not correct for this situation cause it will run this code like this:
Mark::updateOrCreate( [
'student_id' => $student_id,
'subject_id' => $subject_id,
], [
'type_of_exam' => 1,
'times_taking_exam' => 1,
'mark' => 10
] );
Instead, I want this:
Mark::updateOrCreate( [
'student_id' => $student_id,
'subject_id' => $subject_id,
'type_of_exam' => 1,
'times_taking_exam' => 1,
], [
'mark' => 10
] );
I have tried use Mark as Model but I think it's not the best way.
