I have been up and down in costing for quite some time now. Costing stopped me from becoming CA in last attempt. I missed by a mere 7 marks. I have not taken any classes and do not intend to do so in the future. Should i study only institutes module and practice manual?Or please suggest me a good book for self study. Please. Its urgent. Thankyou!
