Why is "We have exams in the spring" not accepted? In English, the future is implied and doesn't have to be explicitly stated.
I'd like to know this too. One guess is that the meaning is slightly different. "We have exams in the spring" may sound as if exams are taken every spring for a sequence of years; "we will have exams in the spring" possibly suggests exams are taken this spring, but says nothing about other years.
I guess the question is how to say "We have exams in the spring" in Russian.
