What did yall infantryman make on the ASVAB to get the 11X option? And what year and age did yall join?

For US Army Soldiers only!!! Just curious because i wanna go infantry, oh yeah because of me graduating on the minimal 24 credit plan instead of Victoria, Texas regular 26 credit plan do u think thats why i'm considered a tier 2 (still got my high school diploma) and my recruiter said i gotta make a 50 is that right? And me askin when yall joined an what age is because my parents say i'm to young to see combat (i'm 18) and i just also wanna know whens a good age to join right after high school or whenever i'm ready? Sorry about all the question its just really wanna join the Army.
