Take notes. The instructor will cover a lot of material during the course, so it's important to take notes. This will help you remember the information and refer back to it later.
Review the material. After each class, review the material that was covered. This will help you solidify your understanding of the concepts.
Practise what you learn. The best way to learn is by doing. Try to practise what you learn in the course in your own work. This will help you understand how the concepts apply to your organisation.
Get help if you need it. If you're struggling with any of the material, don't be afraid to ask for help from the tutor or other participants in the course.
Avoid being distracted. Arrive on time to the class and turn off your mobile phone if possible so that you can concentrate fully on the work in hand.
