It‘s mixed - things are definitely improving, there is no more significant waiting time between ground school and flying. They got rid of most bad ground instructors, but also lost some experienced flight instructors.
Nonetheless be aware that BAA is still BAA. It is and always will be run by the mother company (Avia Solutions), which does not give a single thought about giving students a great time. It’s about the money and you feel that BAA has no real option but to press it through towards the students. Incompetency has greatly reduced, though. They had (maybe thanks to the outrage here... who knows) lots of staff changes and it seems to pay off slowly. Information flow towards the students has also improved. But keeping in mind what has happened to the former students people are still expecting fishy things at every corner, which makes the overall relationship between students and BAA somewhat salty.
The reports from others in this forum are definitely true - they reschedule flying so that you might be forced to rent and cancel apartments in Spain, Kaunas and Vilnius on a short notice and commute between those cities without compensation. But in the contracts they informed you this could happen. Its just that nobody expected them to actually use this to the extent they do. It’s run by a mother company which has an interest in earning as much as possible. ˋnough said. But on the other hand... do other big flight schools behave differently? I honestly don’t know.
They equip you with wrong LogBooks? Good luck trying to get them to equip you with the right one. Sue them for those 40€ or swallow the pill and complain in a forum like PPRuNe (which people do, as you see). Those are the small things which make the relationship somewhat spoiled and leave you with some sort of disbelief, seeing that they actually trying to squeeze the last 10€ out of the students.
Overall - be aware of two major things I’d say: Things like „Wizz is pulling out“ is not true and things like „this place is falling apart“ is also not true. It’s the frustration of students which have been ignored by BAA too long and it needs to unload somewhere. What’s true, however, is the general behaviour of BAA (described by many posters above, so no need for me to elaborate) towards the students in case something goes not as planned. This is what the one poster above means - some sue for compensation, some others swallow the pill and keep on going.
They‘ll train you to get the license you paid for. If you’re satisfied after all is another story.
