I train children, teens and adults for LAMDA exams. Anyone can do an exam and I teach the Shakespeare exams, Verse and Prose and Public Speaking, amongst others (I am not a singing or dancing coach though so you should look elsewhere if doing Musical Theatre exams).
Or you can do the online training with no obligation to do an exam. (May 2020 update: -LAMDA are moving exams online due to Coronavirus).
More about LAMDA exams: https://www.lamda.ac.uk/our-exams Exams are done at a public centre -please see the official LAMDA link below for public centre exam dates and rates paid to LAMDA directly. (Exams@LAMDA.ac.uk can answer further questions).
