Human Factors
I was training in Aircraft X; doing pattern work; and while on final to [Runway] 7R; I was looking out to my left and saw an Aircraft Y starting his turn from downwind to final for 7L. We originally were offset to the right as a precaution for traffic on 7L. As I was getting closer to the runway; I looked back again and saw that the Aircraft Y overshot his base to final turn and was on path to hit us (noticed him about 200-300 feet away). I took evasive action and went full power and a sharp turn to the right to get out of his path. About 3 seconds later he intercepted our path and if not for evasive maneuver; we would've had a mid-air collision.
Student pilot reported an NMAC with an aerobatic aircraft in the pattern at LVK airport.
