What is the difference between shall and should?
The basic difference between “shall” and “should” is that “should” is the past tense of “shall.” But when we use these words or modals, the usage is not as simple as using “should” in place of “shall” in the past tense. “Should” is not used in the past tense independently; it has either present or future reference when it predicates a main clause. “Should” is the conditional form used for “shall.” Occasionally it is used as a past tense of “shall”.
