Simple pagination in laravel? - php

Question

I am working with simple pagination in laravel. I am fetching 20 records from the database in a foreach loop and making a quiz. I want to skip some question in between quiz by applying if condition in controller part...like I want to skip question number 10 and 11. How to proceed in simple pagination?
Controller part :
public function choosequestion(Request $request){
if(Session::get('storepercentage') < 60){
$getquestion = DB::table('5question')->select('question_id','question','choice1','choice2','choice3','choice4','question_level')
->where('question_level','=','easy')
->simplepaginate(1);
}
if(Session::get('storepercentage') > 60){
$getquestion = DB::table('5question')->select('question_id','question','choice1','choice2','choice3','choice4','question_level')
->where('question_level','=','medium')
->simplepaginate(1);
}
if($request->ajax()){
return view('ajax',['getquestions'=>$getquestion])->render();
}
return view('question5',['getquestions'=>$getquestion]);
}
Controller input part to calaculate % :
public function questionquiz5(Request $request){
static $startscore=0;
static $getscore;
static $level;
$getidvalue = Input::get('getid');
$getanswervalue = Input::get('getanswer');
$dbscore = \DB::table('5question')->select('question_id','correct_answer','question_marks','question_level')
->where('question_id','=',$getidvalue)
->get();
foreach ($dbscore as $easy) {//////easy questions start
if ( $getanswervalue==($easy->correct_answer) ){
$level = $easy->question_level;
$getscore = $startscore + $easy->question_marks;
}elseif($getanswervalue == null){
$getscore = 0;
$level = $easy->question_level;
}else{
$getscore = 0;
$level = $easy->question_level;
}
}
Session::push('getscoresession',$getscore);
$score = array_sum(Session::get("getscoresession"));
$epercentage = ($score / 8 ) * 100;
if($epercentage > 60){
Session::put('storepercentage', $epercentage);
echo "true";
echo $epercentage;
}else{
echo "false";
}
Session::push('level',$level);
$getsession = [ 'qid' => $getidvalue, 'answer' => $getanswervalue];
Session::push('answer', $getsession);
}
My issue is that I am getting a blank view for the second condition in simple pagination can we skip question like this?
