How do we know recent and present
I know that present perfect can use present situation and recent action but what I am confused is how to divide them that native speaker is speaking present or recent, how we can know easily? For example
"I have been busy that I have taken an exam for joining speaking class recently."
In this context I used the key word recently to show recent action and actually right now I am not busy and I already did take exam and I am telling recent action by using present perfect as per grammar, what I did.
"I have been busy that I have taken an exam for joining speaking class."
If I omit recently, I will understand that that context means right now I am taking the exam and I am busy, because present perfect show present situation.
My question is - will a native speaker, use to clear the situation present or recent, by using key words recently, lately, of late or how have you been with present perfect? I can easily understand completed action and experiential action but I can't understand how to divide present or recent.
