Our Mechanical Engineering BEng/MEng (Hons) (as our programme has the opportunity for an integrated master's year) lists the following in regards to A-Level Entry Criteria: A typical offer is 112 UCAS points (for both BEng and MEng) from at least two A-levels including MathematicsorPhysics at grade C or above
However, it's best to have a thorough look around at Universities to see which ones offer a programme you gravitate towards, as well as courses you fulfil the entry criteria for, and other factors such as location, student life, and support. Every University differs, either slightly or in some cases more dramatically, so I'd advise to 'shop around' almost - find the right fit for your predicted/achieved grades/subjects and for you as a person!
