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.

Coal bed methane, also known as coalbed gas or coal seam gas is an unconventional gas. It is an important source of energy and currently used as an important source of energy in US and Canada. It is a type of energy resource recovered from the coal seams. Coal bed methane is generally subdivided into three important types: 1. Coal mine methane (CMM)- A kind of coal bed methane releases from coal seams during mining 2. Abandoned mine methane (AMM)- A type of coal bed methane releases from closed and sealed mines, which kept abandoned after coal mining. 3. Virgin coal bed methane (VCBM)- A type of coal bed methane in which recovery of methane is done from unmined coal seams.
