1) Certificate of attending a seminar under the title “.......”.

2) Certificate of attending a seminar under the title of “......”.

3) Certificate in attending a seminar under the title of "....".

4) Certificate in attending a seminar "........ ".

5) Attending a seminar certificate in ".....".

Thanks in advance.
