For preparing Business & Corporate laws who are in the last minute of preparation and have inadequately prepared for the exam follow this,
In Business Laws paper you can omit any two chapters, preferably you can omit Multi State co-operative and Negotiable Instruments Act/Indian Contract Act. The time you save by omitting these two chapters you should revise all the other chapters two times. There will not be any problem in exam as you are making use of choices.
Also in Corporate Laws you can omit any one chapter, but preferably dont omit first chapter which is easy.
