Esol certificate for naturalisation uk

[diwas000007]

Hello somebody please give me a good answer. Basically i am planning to apply for naturalisation as a british citizen. I have passed my life in the uk test and got a ESOL SKILLS FOR LIFE LEVEL 2 CERTIFICATE IN SPEAKING AND LISTENING FROM UNIVERSITY OF CAMBRIDGE. ( i have found out its 2 level higher than the required B1 CEFR) The question is will i just need to provide the certificate( contains 1 certificate) and life in uk pass letter or do i need to obtain a marsheet for the certificate or some sort of letter from college where i passed the exam? I have passed the esol exam and obtained the certificate in 2006. I am sure the certificate does not have an expiry date. Do we need to have a marksheet( where score is given) or will just the single page certificate be accepted? Please kindly help. I am lost.

I believe you'll find you need level 3 for B1 equivalent and also:
For tests taken before 6 April 2013:
Certificate, Statement of Results for each component (reading, writing, speaking, listening), Name of test centre
