This base period covers 12 months and is divided into four consecutive quarters of three months each. The wages you were paid approximately 5 to 18 months before the disability claim begins are included in the base period (they must have been subject to the State Disability Insurance [SDI] tax). Your base period does not include wages paid at the time your disability begins.
Law school is three years long. If you go to an average law school and don't get any tuition help or scholarships, you are going to spend ~$150,000 all-in, at least. That's three years of tuition, assorted fees, books and living expenses.
The most common at my School were Political Science and English, but again those were just the most common not the only degrees there. To get into law school you must take the Law School Admissions Test (LSAT) doing well on it is really the key. I high LSAT score combine with a GPA above 3.0 will generally get you into a law school somewhere.
