Salvete! I studied Latin at the beginning of secondary school. Almost 20 years later, all I can remember is Caecilius est in horto and the present tense conjugation of amare 
. To be honest, I didn’t really understand much at the time, as no one ever explained to me the meanings of terms like “accusative” and “nominative”!
I’m considering making a proper attempt at learning Latin again, although I’m currently also learning Spanish, and I may wait until I’m a bit better at Spanish before I begin Latin properly, as the two can be confusingly similar in places. For example, compare the conjugations of Latin’s esse and Spanish’s broadly equivalent ser.
sum, es, est, sumus, estis, sunt
soy, eres, es, somos, sois, son
I’m very interested in methods for learning correct classical pronunciation, and when I start learning Latin in earnest, this is where I will probably start.
