The CLAT syllabus comprises everything you can get in a general competitive exam. For English, Mathematics and Logical Reasoning you can either follow the previous year papers and devote an hour everyday pouring onto the questions or you can purchase a test series and try to take tests whenever you get time out of your studies. For current affairs and legal aptitude it is necessary to devote some time daily so you can give 30 minutes to prepare for each section. And that's how contributing 2 hours daily you can easily get through it.
