No need for you to return for two more years to learn the Track (CV or General Ultrasound) you didn't choose at your start. You'll gain competence STAT and forever spend the difference it makes, for the rest of your Career. Micro-classes ongoing in Dallas, Texas since 1981.
I learned deeper practical skills here than I even did in School-- and that experience was excellent. I'll be back for more.
