Answer

look at these examples
1- you studied - أنت درستَ    ___ ta___ the addressee is male here
2- you studied أنت درستِ  ___ ti___ the addressee is female here
3- I studied - أنا درستُ___ tu
4- she studied هي درستْ _____ t.

all the examples above are in the past tense
As for the present tense
she studies-- هي تَدْرُس
you (male) study أنت تَدْرُس
the same writting and pronounce but the context helps here

Answer

do you mean verbs, if yes well you can never say ( taridu) but if you mean generally verbs then I think this link might help( hope it could help :) )  but I think it's kind of hard to memorize therefore I think the best way is just to read alot so you will be able to feel the language, cause arabic is also a language that depends on it's sound, like you can know from  hearing it if it's wrong or right. anyway here is the link:
