Do I need to take the SAT Subject Tests?

I know that some colleges require Subject Tests, but there are a lot that don’t. I am planning on going into some type of engineering and someone I know who is in engineering school now never took them but I’m not sure if I should take it so I have a chance of getting into as many school as I can. What should I do?

Not very many colleges require subject tests. About 30 or so and about half these will accept the ACT Plus writing in lieu of Subject tests. So, if you plan on applying to some of the top 50 or so colleges you should take subject tests
