BY, you need to define what is a “good” university that you will want to attend and plan accordingly. Gadol seems to think that this got to be an Ivy. On many other places, you can get solid education as long as you are taking a harder version of each class in a non-fancy school.
Are you are looking for a career path where you are super-employed full time at a law firm or a trader? Then, you probably need to go to an Ivy. Are you planning to learn a trade, like software developer or a nurse, or an engineer? Then, you can do well with a state school or an online school if you don’t want to dorm in a non-observant place. Also, take into account our family finances. If your parents work and are paid well, they better be prepared to pay a lot for luxury colleges like Ivy or Jewish ones, it would be more rational to go to a less fancy college. If your family is not well off and you get great grades, you can get a scholarship and plan to get to MIT or Columbia.
