Some Trainees pay a college to sudy Part 1. However, it's possible for anyone to purchase the official recommended reading material (listed here) and study at home in their own time.
For that reason we always point out that training for the Theory Test and Hazard Perception Test (HPT) with DITA is a home study course using the recommended reading material.
The DITA Part 1 pack will provide you with a booklet on how to go about training and preparing for the Part 1 tests.
We can also provide support should you require it. The good news is that it can be done at your own pace, around other commitments you have.
Remember: The theory test is a very important 'foundation' for the rest of the course. The information that you learn here will reflect in your driving on the ADI Part 2 and become an essential part of the preparation for the ADI Part 3.
