I am considering attempting the physics praxis to add to my Biology and Chemistry endorsements (7-12) but I am also unsure if I really want to spend the time/money when the bio/chem endorsements should be more than enough for me find employment in the areas I am interested in. I have been given the advice of "the more endorsement the better, especially in high demand areas" and on the flip side "you are already endorsed in a high demand area, stick with what you have". I know I can only decide for myself, but I would love to hear what others have to say. Any pros/cons??
