    private  void rescheduleBurstSMSResponse(){

        try{

        Datetime dt = system.now().addMinutes(1);          

        String day = string.valueOf(system.now().day());

        String month = string.valueOf(system.now().month());

        String hour = string.valueOf(system.now().hour());

        String minute = string.valueOf(system.now().minute());

        String second = string.valueOf(system.now().second());

        String year = string.valueOf(system.now().year());

        

        String cronExpression = '' + dt.second() + ' ' + dt.minute() + ' ' + dt.hour() + ' ' + dt.day() + ' ' + dt.month() + ' ? ' + dt.year();

        String strSchedule = '0 ' + minute + ' ' + hour + ' ' + day + ' ' + month + ' ?' + ' ' + year;

 

            

            if(Test.isRunningTest()) {

            //This will throw Divide by 0 error and code will move to catch block

            Integer divideError = 123/0;

        }

                System.schedule(cronExpression, strSchedule, new ScheduleServiceClaim());

        }catch(Exception ex){

            System.debug(ex);

            System.debug(ex.getMessage());

            System.debug(ex.getLineNumber());

    Yes It is possiable. 

    Salesforce does not allow to schedule bach class every minute. But you can use trick to schedule it for every minute.

    Use a function and run a for loop to schedule the class for every minute for 1 hr. 

    Example :

    Like  schedule 4.05 ---> after one hr it will run at 5.05.

    then for 4.06 ---> it will run again at 5.06.

    for 4.07 ---> will again run at 5.07.

    This is how schedule it for 60 times for every minute. Every minute will execute after 1 hr which is allowed.

    Here is the function and CRON EXPRESSION that runs every minutes

     

    // CRON EXPRESSION to schedule per minute in salesforce
    global static void runSchedule(){
            for(Integer i =0; i < 60; i++){
               String CRON_EXP = '0 '+i+' * * * ?'; 
            	GenericRecordSchedulableClass gensSch = new GenericRecordSchedulableClass();
            	System.schedule('Generic every min'+i, CRON_EXP, gensSch);
            }
        }

    If it helped you. support this answer.
