Assuming you have eight weeks or more for the test, here is what i can recommend. Sure, you will have to adjust accordingly depending on how many hours /day you intend to prep. I hope my advice helps you.
Study the Official Guide entirely from the first page to the last in a month. Try practising in sets. Say, 40 PS/ 25 DS / 5 RC/ 15 CR / 25 SC. Follow this sequence or something that suits you for a month. Make notes of your errors and study them everyday. Please make these notes very neatly so that you can use them at the end of the prep.
After a month, try studying with kaplan
materials. All this while, keep updating your error logs. for math, you may also try practicing with the challenges that we have held in the past. for verbal, i would suggest you got get LSAT material AFTER you are done with OG. take atleast two kaplan
practise test of the 4. Sure, they will be tough, but its kinda helpful in building up your concepts.
Ninth week of prep: Now, you will have spent 4 weeks prepping without the OG. In your ninth week of prep, take Powerprep 1. Sure , you might remember some questions from the OG. but i think most of the test will still be new to you.
Tenth and final week: Take Powerprep 2. Now is the time that your hard work with the error logs will help. Study the problems that you got wrong every day in your final prep week.
Finally, relax and go take the test!
