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.

Usually I think they give you proper units to write in the main exam. But even if this thing happen that they don't give you unit to write then yoiu should go according to the question. If the data has Nanometer as unit then you should consider Nanometer. If it has Angstorm then mention Angstorm. If it's mixed then they surely would given you unit to write. Even then also it's not there then you should go with Angstorm. But I feel they do provide units.
