Hello, firstly I wanna take the chance to thank you for the huge effort that you offered and GOD BLESS YOU.
secondly I really need your help in writing an email since I'm not good in righting either emails or letters even in my native tongue.
My situation I have diploma in electronics engineering and I wanna email some universities enquire about completing my study doing bachelor in biomedical engineering. Also I wanna enquire about credit transfer since I'm coming from electronics engineering to biomedical engineering.
I will be patiently waiting for you help
