public DemoClass {
    mapFieldLabels = new Map();
    Schema.DescribeSObjectResult d =   Application__c.sObjectType.getDescribe();
    Map mapFields =   d.fields.getMap();
    for (Schema.FieldsetMember member : getEnrollmentQuestionsFields()) {
        if (member.fieldpath == 'Entry_Type__c') {
            mapFieldLabels.put(member.fieldpath,'Entry status'); 
        } else if (member.fieldpath == 'Start_Term_of_Interest__c') {
            mapFieldLabels.put(member.fieldpath,'For which term are you applying?'); 
        } else if (member.fieldpath == 'Start_Year_of_Interest__c') {
            mapFieldLabels.put(member.fieldpath,'For which year are you applying?'); 
        } else if (member.fieldpath == 'Academic_Areas_of_Interest__c') {
            mapFieldLabels.put(member.fieldpath,'List the academic areas in which you have the greatest interest'); 
        } else if (member.fieldpath == 'EnrollmentrxRx__Do_You_Plan_to_Apply_For_Financial_Aid__c') {
            mapFieldLabels.put(member.fieldpath,'Will you apply for financial aid?'); 
        } else {
            mapFieldLabels.put(member.fieldpath,mapFields.get(member.fieldpath).getDescribe().getlabel()); 
        }
    }
