psw letter from university

hi, i came to uk 4 years ago on student visa and completed my bachelors degree and next week i am going to apply for psw visa. i have a doubt regarding a letter from university. In the application form section H
H2:
Tick the box to show that the applicant has sent an original letter from the academic institution as evidence that the United Kingdom institution is either a United Kingdom recognised, United Kingdom listed body or holds a sponsor licence under Tier 4 of the points based system..


so what evidence could i produce for that? i asked the psw visa letter and the university gave me letter with the details..

student name:
D.O.B:
Course level & title
start&finish date
date of award
date of graduation
the above course was taught in english at a u.k recognised body ...XXXX university is the awarding body.all successfull candidates will be issued with a certificate after graduation..

is that letter is sufficient ? please advise me...
thank you...
