Hi there,

According to today's press release by NLU Consortium pattern for CLAT 2020 has been changed and now there will be 120-150 questions rather than 200 and questions from deductive reasoning and english will be  comprehension based questions, this is change from the earlier pattern of questions. Deductive reasoning is basically logical deductions made from a statement in my opinion A modern approach to logical reasoning by R.S Aggarwal cover questions on deductive reasoning which are comprehension based so you can refer this book for your deductive reasoning questions. Now coming to English, Wren and Martin and Word Power Made Easy by Norman Lewis will help you in this section
