Based on the information below can someone tell me where I went wrong on the Microsoft project WBS

Next create the Work Breakdown Structure (WBS) for your project. You will need to have at least 20 tasks. You should break the work down to a level 2 or 3 as needed or appropriate. Next, you will add the durations for each of the tasks to your Wordbreak Down Structure. Then add the dependencies to the tasks as necessary. All of this should be entered into Microsoft Project using the course start date as the project beginning date.

Once you entered the information for your WBS into MS Project, create the Gantt Chart, identify the critical path(s), and identify some of the milestones for your project.

The deliverable for this part of the project will be a formal letter to your supervisor (your instructor) that explains your WBS and the relevant information derived from the WBS. The letter should include attachments of the Gant Chart showing the Critical path.

You will submit the letter as a Microsoft project
