I am a learner of English and I have been learning it for the last few months. I wrote a definition of the present perfect tense. Please check the definition and let me know that I have been using it perfectly or not. I am a little bit confused about it.
The Present Perfect Tense:
1->An action started in the past but it has just finished or maybe not (as per me both options are possible).
2->An action started in the past and it has just finished but its result matters in the present.
