In British English, 'just' is often used with the present perfect tense (e.g., 'I've just arrived'). In American English, it's common to use 'just' with the simple past (e.g., 'I just arrived'). 'Just' can also be used to suggest something was barely achieved, e.g., 'He just managed to pass the exam.' Be cautious about placement. 'Just' should be placed before the main verb or before the verb 'to be'. For instance, 'I just have seen him' is incorrect; it should be 'I have just seen him.'
