I am currently pursuing ca,2nd level and bcom 3rd year, will cwm help me to grow my career in finance sector?Can I learn it within 1 month?

For my 3rd year of articleship I want to go for industrial training in invt banking.The main reason behind pursuing CWM now (i.e. before start of articleship) is that ICAI doesn't allow ca students to pursue multiple course during articleship,so I want to complete cwm before it.Castudent,bcom3rd yr.
