now since there are only 1.5 months left for exams,since you already studied something from padhuka,i suggest you to get munishbhandari handbook and study it for the remaining time,since it is a law subject you can change book as law is same in any book,but just how it is presented is more important,also paduka is a good book,but munishbhandari book is well presented in a easy manner to revise before exams.
also in the handbook only those sections are covered which are repeated mostly in the exams.
