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.

Organic chemistry can only be learned by practicing. There is no shortcut. The reagent is mixed cuprate. The mixed cuprate has the formula Li2[Cu(2-thienyl)(CN)R] is prepared by combining thienyllithium and cuprous cyanide followed by the organic group to be transferred. In this higher order mixed cuprate, both the cyanide and thienyl groups do not transfer, only the R group does. I am sending the product and reference for more information https://books.google.co.in/books?id=z2LgBwAAQBAJ&pg=PA480&lpg=PA480&dq=Li2%5BCu(2-thienyl)(CN)R&source=bl&ots=UlrjKvup0e&sig=ACfU3U3-4YRIQlOVwMugSkKiHjuCTkJHxg&hl=en&sa=X&ved=2ahUKEwjQ2Ln76LTpAhV79nMBHXwIAFkQ6AEwEXoECAUQAQ
