Delta
Delta involves three modules: the exam (Module One), the coursework portfolio (Module Two), and the extended assignment (Module Three). You can do one, two or all three of them. You will receive a certificate for any module you pass, but if an institution specifies that you should have the Delta, they usually require that you should have passed all three.
Part-tIme or INTENSIVE?
The Delta is an extremely demanding course. If you can do Module Two part time you have more time to absorb ideas, try them out and make changes in your practice. Most people on the part time course complete their portfolio in six months. The work in the portfolio you submit should be dated within the year leading up to your submission date, so while there is some flexibility if it is needed, once you have started Module Two you need to complete and submit. The fact that it usually takes six months is both the main advantage (you have more time to do things) and the main disadvantage (it will have a significant impact on your free time for most of that period).
If you do Module Two intensively you complete most of the written assignments and all of the assessed LSAs (background assignments and lessons) in the space of six weeks. The fact that it takes six weeks is both the main advantage (your life will be dominated by the Delta for a shorter period of time) and the main disadvantage (it makes the course very very pressurized). You will eat, sleep and breathe Delta for that space of time. You should not be doing anything else. If you come to Ankara to do it, you will not have much chance to see the city. Plan sightseeing before or after the course. The intensive version of the course immerses you in the experience and has a higher rate (around 90%) of participants who complete and submit than the part time course.
