B.Sc. Bachelor of Science
M.Eng. Master of Engineering
An M.Eng. is a integrated additional year so you would achieve a B.Eng. after completing year 3 of studying, and it is likely that you would have discussed this by the middle of year 2, such as before going on a placement year, so that when you return you know that you will now do another 2 years of study and complete an M.Eng.
An M.Eng. means you would be entitled to government student loan like someone studying for a B.A. or B.Sc., where as in previous years a M.A. or M.Sc. would have had to apply for bank funding, this year as is unavoidable to know that you can now get a government funded postgraduate loan.
So you can see on an Engineer's CV, M.Eng., M.Sc., Ph.D. for example. So you now understand that this person has done an additional integrated masters level study year and an entirely independent M.Sc. study year that is highly likely to be specialising and as shown, a Ph.D. just to look like a possible CV.
