"I were" is only used in the conditional. "If I were a graduate, I would be making more money." "If I were taller, I could play on the basketball team." You will never see or here "I were a graduate." You will here "If I was" a lot. Strictly speaking, "If I were" is the correct form, but "If I was" is used so much that even English teachers have given up correcting it. And naturally, "I was going there", as simple past tense, is always correct. If you were using past tense, you would only use "were" with 'they', or 'you'.

Was is singular and applies to one person. Were is plural and applies to more than one person. (except in singular "you were") i.e. "I was ready, but you three were not ready." "Were" is also the past subjunctive of the verb "to be" for all persons i.e. "If I were in charge, I would fire her." "If she were here, you would see her." "I wish I were rich."

Hello, Merna! My name's Caesar (as the Roman emperor). I'll give you an explanation and examples. I'm hoping this will be helpful. In the first sentence I am talking about a possibility of how things WOULD be but are NOT. In other words you use "I were" only when you talk about possibilities. EX: "If I >were< from Egypt[, then] I >would< speak Arabic. But since I am NOT from Egypt[, then] I do NOT speak Arabic." EX: "If I were rich like my aunt[, then] I would take a trip to Egypt, Germany, Italy or Sweden. But since I'm NOT[, then] I cannot enjoy such pleasures of life" EX: "If I were the president of Egypt[, then] I would abolish censorship. But because I'm NOT[, then] I cannot do anything about it."

"I were’’ is one of the few remaining examples of the subjunctive mood in the English language. The subjunctive is not a tense; rather, it is a mood. Tense refers to when an action takes place (past, present, future), while mood merely reflects how the speaker feels about the action. The subjunctive mood is rarely used in English, but it is widely used in Spanish. The subjunctive mood is used to express everything except certainty and objectivity. It espresses things like doubt, uncertainty, subjectivity, a state of unreality such as a wish, emotion, possibility etc. Examples: be that as it may blessed be ! far be it from me if need be truth be told I wish it were summer. Harris was determined that the film be authentic. If only the weather were this reliable. I wish it were enough. If I were a rich man, I wouldn't have to work hard. If I were a rich man, yubby dibby dibby dibby dibby dibby dibby dum. (a song)

THANKS ALL FOR THOSE HELPFUL ANSWERS <3 :)
