Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

It is somewhat similar to parting lineation (may be there is a typo). Well you might be aware of the fact that plane beds are lower flow regime related sedimentary structure while in an upper Flow Regime where the power of stream flow washes out ripples and dunes, replacing them with plane bed then this kind of plane bed commonly has parting lineation. Refer Sam Boggs for better idea and deeper insight about these upper and lower flow regime structures depending on the flow velocity.
