You must go and have a trial flight before signing-up. Is there a flying school or a GA airfield nearby? They should be able to fix you up.
A Cessna 152 for example is quite primitive. The cockpit is small, and you sit literally rubbing shoulders with the instructor. It is very hot (or cold), very noisy, cramped and basic. The construction of the doors etc, seems very flimsy and almost like a toy. Might put you off for life.....
A PA 28 is better and more like a "real" aeroplane, but still quite basic.
You must go for a trial lesson or an hour fun-flight to experience it for real before committing
Regarding the exams, I would say that 2 weeks from no knowledge to passing exams is not sensibly possible. You need time to read up and fully understand everything. The Trevor Thom PPL book series has six volumes, which will take longer than 2 weeks to fully read, learn and understand and assimilate everything properly, never mind practising all the mathematical processes and learning the knowledge. I would give it 6 months at the very least.
Anyone who claims it can be done ab initio in 2 weeks is, frankly, talking nonsense. They sound to me like they just want your money.
I would also caution against practising test questions just to pass the exams without really understanding anything. You really need to gain the deep knowledge to fly - especially as a PPL, where you might be solo or the only pilot on board. You don't want to get into danger because you don't really understand something.
