We report on magneto-transport measurement in disordered graphene underpulsed magnetic field of up to 57T. For large electron or hole doping, thesystem displays the expected anomalous Integer Quantum Hall Effect (IQHE)specific to graphene up to filling factor $\nu=2$. In the close vicinity of thecharge neutrality point, the system breaks up into co-existing puddles of holesand electrons, leading to a vanishing Hall and finite longitudinal resistancewith no hint of divergence at very high magnetic field. Large resistancefluctuations are observed near the Dirac point. They are interpreted as the thenatural consequence of the presence of electron and hole puddles. The magneticfield at which the amplitude of the fluctuations are the largest is directlylinked to the mean size of the puddles.
