1. If you are starting from scratch with little to no SAT preparation, you can expect to spend around 100-200 hours going through the entirety of a comprehensive SAT prep book. This estimate assumes you are studying for about 2 hours per day, 5 days per week.
2. If you have some prior knowledge of the SAT and have taken a practice test or two, you may be able to complete a prep book in a shorter amount of time, say 50-100 hours.
3. If you are an experienced test-taker with a strong understanding of the SAT format and content, you might be able to skim through a prep book and focus only on the sections you need more practice with, which could take around 25-50 hours.
4. Additionally, if the prep book includes timed practice tests or full-length practice tests, it's important to factor in the time it will take to complete and review those tests. Each practice test can take several hours to complete and analyze.
Remember that these are just estimates, and your actual study time may vary. Consistent daily practice and a systematic approach to SAT prep will help you make the most of your prep book and increase your chances of achieving your desired SAT score.
