Narrative:

We are at 3;000 feet; finishing our last (3) holding west of zzzzz. My instructor told me that the oil pressure was very low and he also notice an increase on the oil temperature. We both notice a low in the performance of the plane. And my instructor; told me: 'my controls'; so I gave him the controls in that moment'; suddenly; we start to hearing a strong rough engine sound and loss of strength and power by the engine. My instructor told me to put on the GPS north ZZZZZ1; but the vibration was so hard that I did barely could put the point on the GPS; and at the same time my window star to open three times; also my door; so I did manage to close it and we began to loose altitude. On top of that in that particular moment; the engine stop completely; my instructor ask me to start looking for the best place to land; so I did. In the meantime that my instructor was controlling and doing the procedure; I suggested a small field that was a side of a small construction that look like a rural house in the middle of the everglades. My instructor did the whole configuration for an engine failure during flight: glide speed (65); turn on the carb heat; fuel selector on both; mixture full rich; magnetos restart; primer in and locked. My instructor; in order to verify everything; ask me to take my check list and I did give it to him; so my instructor repeat the procedure twice. Suddenly; we both looked that a dark smoke start getting into the cockpit. We start descending but in that area in some part was a lot of trees that could make our landing very dangerous; that's why we start heading to the swampy [area]; that was considering the circumstances the best place to try to make the landing. When we was getting closer and descending we had a few words when we both prayed; and after that my instructor start doing the landing procedures; so he cut off the mixture; airspeed 65; magnetos off; zero flaps; master off; doors open. We start touching the surface and start getting contact with the grass and vegetation with was very thick and tall; so in a point the airplane flip over; crashing up side down hitting the surface of the everglades. We crash upside down with the windshield and the water start getting in the cabin; and we were for a few seconds stuck with the seat belt; we release from the seat belts but my instructor's door was locked; so I managed to kick and open my door; so I did exit first. As soon I was out; I did help my instructor to get out of the plane and we both stay on the wings; and we start doing all the call. I call [for assistance]; and my instructor called the school; the rescue arrived 1 hour later.
