Don't take histology, take Spanish. In fact, take it every year until you are completely fluent. I swear, being able to speak Spanish will benefit you more than any class you will every take. I have at least 25% of my patients who don't speak English, and if I couldn't communicate with them and they couldn't bring a translator, they wouldn't get any treatment at the school. You may hate every minute of it, but being bilingual (Spanish/English of course). There is literally almost an equal number of hispanic and white people in Texas (
