Practical (Set Tasks)
Develop a checklist for determining the significance of pests and diseases, which addresses different criteria including:
- Short term impact
- Long term impact

Assessment is based on a combination of completing all assignments and sitting for a final short one and a half hour exam, in your own location.
If you don’t cope well with exams then you may elect to undertake a project instead. This is a popular option.
In addition, most modules have a Set Task at the end of each lesson placed before the assignment. This is an opportunity to undertake practical work to help you acquire knowledge and skills and practical experience. This ADL feature is an added bonus not found at most online schools. Set Tasks are not required for assessment.
Some courses also have optional Self-Tests which are available on our online learning platform. These are not available by correspondence or by USB, and do not form part of your overall grade.
How our courses work
- Choose Your Learning Method
You choose how you would like to receive your course material, i.e., Online, USB or Correspondence. The choice is yours. You may also work on online or offline.
- Tutor Allocation
Every student is assigned their own dedicated tutor who is an expert in their subject area. They provide as much or as little individual contact as you require. You can contact your tutor whenever you need – your hours are not limited.
- Feedback and Assignments
Tutor Feedback is an essential component in helping you understand the subject matter. Tutor feedback is given in the form of notes written on the assignment. We encourage you to contact your Tutor where help with clarification and understanding of course material may be required.
Your assignments are located at the end of each lesson. You submit them for marking whenever you are ready. There is no time limit.
- Set Tasks and Self-Tests
Most modules have a Set Task at the end of each lesson before for the assignment. This is where you get the opportunity to undertake practical work to help you acquire knowledge, skills and practical experience. Many modules also have short Self-Tests.
Once all assignments have been completed you may then elect to sit for a one and half hour exam in your own location. If you prefer not to take the exam you do have the option to undertake a project instead.
Once the exam or project part of the course is completed, your Certificate is then processed. Please allow approximately 4 weeks for this.
