How to schedule apex class every 5 mins

Hi,  

I have written a apex class , in which I need to schedule that class every 5 minute.  

I tried executing below Approaches : 

Option 2: This executing every 5 mins per hour
 global with sharing class ScheduleBatchApexDemo implements Schedulable {global void execute(SchedulableContext sc) { PricingEventReviewAggregatorContract.createPricingLogItemsContract();}Public static void SchedulerMethod() {  string timeinterval = '0 5 * * * ?';  System.schedule('ScheduledDemo-Every5mins',timeinterval, new ScheduleBatchApexDemo());  }}

Please help if there is any optimized approach

Option 1 : Executed code in anonymous window. But I dont want to have n number of scheduled Jobs. System.schedule('Schedule Job Name 1',  '0 00 * * * ?', new ScheduleBatchApexClassExample());System.schedule('Schedule Job Name 2',  '0 05 * * * ?', new ScheduleBatchApexClassExample());System.schedule('Schedule Job Name 3',  '0 10 * * * ?', new ScheduleBatchApexClassExample());System.schedule('Schedule Job Name 4',  '0 15 * * * ?', new ScheduleBatchApexClassExample());System.schedule('Schedule Job Name 5',  '0 20 * * * ?', new ScheduleBatchApexClassExample());System.schedule('Schedule Job Name 6',  '0 25 * * * ?', new ScheduleBatchApexClassExample());System.schedule('Schedule Job Name 7',  '0 30 * * * ?', new ScheduleBatchApexClassExample());System.schedule('Schedule Job Name 8',  '0 35 * * * ?', new ScheduleBatchApexClassExample());System.schedule('Schedule Job Name 9',  '0 40 * * * ?', new ScheduleBatchApexClassExample());System.schedule('Schedule Job Name 10', '0 45 * * * ?', new ScheduleBatchApexClassExample());System.schedule('Schedule Job Name 11', '0 50 * * * ?', new ScheduleBatchApexClassExample());System.schedule('Schedule Job Name 12', '0 55 * * * ?', new ScheduleBatchApexClassExample());
