Hey.

Here are some if the books that you can use to prepare for MHCET Law.

You can use an all inclusive guide like Universal's guide to LLB and CLAT which includes basics and practice questions for all these topics. You can also use the Arihant's guide to MHCET.  Other than that you can refer to previous year question papers for The  entrance for a better guidance. For current affairs and verbal section the Hindu is considered as the best newspaper. You can use Word power made easy- Norman lewis for vocabulary. You can use R.S aggarwal'a books for Logical Reasoning or quantitative section in case you need a separate book other than universal's guide.
