BVMDAE(Bachelors Validation/Masters & Doctorates Access Exam)
**

You are in possession of Master's or Doctorate's Degrees from other institutions you still have to pass the BVMDAE.

**Whether you studied at Oxford, Harvard, Cambridge, Yale, Open University, UNISA, SAIM, IBS, ICS, Intec, Alison, Coursera or Fun MOOC, you have to pass the BVMDAE(Bachelor's Validation/Master's & Doctorate's Access Exam). The BVMDAE will become the future Educational level Evaluation tool. The BVMDAE has for goal to keep the highest standard possible. Take note that Oxford, Harvard, Cambridge and Yale students have difficulty to pass the BVMDAE.**

**EIPG Online Vocational education**(and what is ...) can take place at the post-secondary, further education and higher education level; and can interact with the apprenticeship system. At the post-secondary level, vocational education is often provided by highly specialized trade, Technical schools, community colleges, colleges of further education UK, Universities, Institutes of technology / Polytechnic Institutes etc.

Until recently, almost all vocational education took place in the classroom, or on the job site, with students learning trade skills and trade theory from accredited professors or established professionals. However, online vocational education has grown in popularity, and made it easier than ever for students to learn various trade skills and soft skills from established professionals in the industry.

What about Recognition ... The

**BVMDAE(Bachelors Validation/Masters & Doctorates Access Exam)**serve as an automated recognition exam. Most Public University students fails this exam so do not take this Examination for Granted.

**Magnesium aluminate**, Synthetic spinel, accidentally produced in the mid-18th century, has been more recently described in scientific publications in 2000 and 2004. By 2015, transparent spinel was made into sheets and other forms by sintering. Synthetic spinel, which looks like glass but has a significantly higher resistance to pressure, can also have applications for military and commercial purposes.
