There is no substitute for experienced, professional instruction. From your first day in theory school, to your retirement in many years time, the success of your career will be largely influenced by the quality of the school you select now. Until you have actually sat down with the staff and instructors at the various schools, you won't know if you are going to feel personally comfortable with those people. It is very easy to exaggerate in a brochure, however it is only when you are actually there in the building that you can really judge the quality of the facilities. You don't want to spend week after week in theory school sitting on a plastic chair behind a wobbly folding table, or find your flying briefings are done on a picnic table behind the school, while the helicopters start up beside you.
Ongoing support comes in a variety of forms like advanced theory training and flight training.
You should be planning your future now. For example even the most experienced mustering pilots eventually feel the need to move on to other types of flying. By making the right contacts now, the progression will be easier when that time comes. Be cautious of offers by people who don't even know you, but guarantee you a job on completion of your training. Many other students would have been promised the same thing.
