# IBM apprenticeships: who can apply and what to prepare

## Catch bad records before calculating the average

Original fictional support log. All times refer to the same day and timezone. A resolved ticket needs a valid start and end time; an open ticket does not yet have a completed duration.

### Four input rows to test

| Ticket | Status | Opened | Resolved |
| --- | --- | --- | --- |
| T1 | Resolved | 09:00 | 09:20 |
| T2 | Open | 09:10 | Blank |
| T3 | Resolved | 09:30 | 09:20 |
| T4 | Resolved | Unreadable | 09:50 |

## Your turn

Which records can support the completed-ticket average? What else must the report disclose?

## Your answer

[Write your approach here.]

## For your own application

Add a small test file to your project with valid, open and invalid records. Make the exception count visible beside the reported metric.
