Hello aspirant. Firstly, the subjects are english, mathematics just the basic maths, GK, legal aptitude and reasoning. Hope you would be aware of the syllabus. If not, drop a comment, I will help you with that.

1. English... usual ones like, blanks, synonyms, passages so on and so forth. Practice the previous year question papers

2. Basic mathematics .. algebra, work and time, Quant of basic level, distance etc ..practice RS agarwal books and ncert books bits, it would be more than enough. But practice daily

3. GK... get to know all the static gk question and answers that are constant. Regarding current affairs ,follow news and news paper daily. If possible note down the issues going on for long time

4.legal aptitude .. solve the current legal problems, read the case studies given in the net that are solved before related to legal problems. The many you solve, the better it would be

5. Reasoning.. again, practice rs agarwal book, previous reasoning and non verbal questions. Solve the test papers

All the best
