Answer 1

Ok, now I see the problem.
In index method of controller you use
$exam_scheds= Exam_sched::paginate(3);
but in create method you use:
$exam_scheds=Exam_sched::all();
and you use same view in those 2 methods.
Of course when you use all() method there is no pagination so you cannot use links then in view.
So probably you should change in create method to also paginate same as in index method.
