[Vocabulary] Is practica a correct English word?

[bart_b]

Hello there,
I have to hand in a school research paper next week. I'm doubting about using practica or experiments as a word for the plural form of practicum. Is practica a known word for English natives?

Thanks in advance,
Bart

It is not well known. I would avoid it in your paper.
