This paper is on impacts of inclined magnetic field and multiple boundary layer slip flow of convective MHD Casson fluid through an exponentially stretching porous sheet in the presence of viscous dissipation, thermaldiffusion, diffusion-thermo and thermal radiation. The non-linear boundary layer partial differential governing equations of the flow are converted using appropriate similarity transformations to non-linear coupled ordinary differential equations (ODE). The resulted momentum, heat and mass equations are solved using collocation method based on assumed Legendre polynomial. Velocity, thermal and solutal slip, inclined magnetic field, Casson fluid parameter and other physical features have been discussed and elucidated in tables and graphs. Velocity, thermal and solutal slip declined significantly the velocity, temperature and concentration distribution respectively toward the stretching sheet, while at the free stream, the effect is not noticeable .
