The announcement of exam results also wrapped up without any trouble, and naturally everyone's immediate attention is turning to summer vacation now, right?

Literal

Test-results announcement [also-も] without-incident-[つつがなく] ended-[and-て], immediate-[attributive-の] focus [subject-が] naturally summer-vacation [to-に] gather-[come-てくる][confirmation-でしょ]?

Casual conversational musing. つつがなく ('without incident, safely, without a hitch') is a literary adverb from つつが ('trouble, hindrance') + なく ('without'). 当面 ('immediate, for the time being') is a common adverbial. 自然と ('naturally') contrasts with 自然に — both mean 'naturally' but ~と often has a slightly more definite or inevitable feel. でしょ (contracted でしょう) invites agreement.
