I m new to salesforce and can't find what this Page refers to in this code...is it a class or something else...?

public PageReference save() {

                PageReference p = null;
if (this.qp == null || !'yyyy'.equals(this.qp)) {
                    p = Page.failure;
                    p.getParameters().put('error', 'noParam');
} else {
                    try {
Lead newlead = new Lead(LastName=this.lastName,
                                                FirstName=this.firstName;
                                                Company=this.company,
                                                Email=this.email)
                        insert newlead;
                    } catch (Exception e) {
p = Page.failure;
                        p.getParameters().put('error', 'noInsert');
}

                }



                if (p == null) {

                    p = Page.success;

                }
   p.setRedirect(true);
                return p;
            }

Error in Vf Page Unknown Property 'visualForceArrayList.'

Hello, I am just new to salesforce and cannot figure out why iam getting this error....and trying a lot and lots of searches....
So, this is my controller code...where i am declared List<> variable...

public class OnlineExamController
{
    public static String selectedExam{get;set;}

    public List<OnlineExam__c> o{get;set;}

    public List<Integer> iter{get;set;}

    public OnlineExamController(ApexPages.StandardController stdController)
    {

    }

    public OnlineExamController(){}


    public List<SelectOption> examName
    {
        get
        {
            examName=new List<SelectOption>();
            examName.add(new SelectOption('----None---','----None---'));
            examName.add(new SelectOption('DAV_401_EXAM','DAV_401_EXAM'));
            examName.add(new SelectOption('DAV_402_EXAM','DAV_402_EXAM'));
            examName.add(new SelectOption('DAV_403_EXAM','DAV_403_EXAM'));
            examName.add(new SelectOption('DAV_404_EXAM','DAV_404_EXAM'));

            return examName;
        }
        set;
    }

    public PageReference call()
    {
        system.debug(selectedExam);
        o=[Select Questions__c, A__c, B__c, C__c, D__c, E__c, Answer__c, Multiple__c, ExamName__c From OnlineExam__c];
        system.debug(o);
        iter=new List<Integer>{0,1};
        return null;
    }
}
Ad this one is my vf page code , just showing the part which is causing the error because the whole code is too big...to display...

<apex:page controller="OnlineExamController">
<apex:form>
   .
   .
   .
<div class="slds-form slds-form_stacked" style="display:block;">
            <div class="slds-form-element" style="width:100%; margin-top:5%;">
                <div style="float:left;">
                    <label class="slds-form-element__label" style="font-size:20px; margin-left:20px; text-align:left;">Question No.1</label>
                </div>

                <div style="position:relative;float:left; width:70%; margin-left:10px">
                    <b style="font-size:20px;">
         (--PART--------<apex:repeat value="{!iter}" var="pos">
                            <apex:outputText value="{!o.[pos].Questions__c}"/>
                        </apex:repeat>--------CAUSING ERROR---------)
                    </b>
                </div>
            .
            .
            .
            .
</apex:form>
<apex:page>

Thanks in advance.
