The review thing means you've been put forward into a pool because they're not going to offer you anything just yet. If they come back in December and ask you to do a part 2 med you'll have to do and ECG, chest x-ray, blood test and an EEG (brain scan).
Assuming you pass that you should be in, unless the system has changed. They should send you a letter saying that you've provisionally been selected for pilot pending the outcome of a part 2 medical if they're going to accept you.
