UPSEE Answer Key 2018

UPSEE 2018

Admission to various courses like B.Tech/B.Arch/B.Pharm/BHMCT at Dr A.P.J. Abdul Kalam Technical University, Uttar Pradesh, formerly known as Uttar Pradesh Technical University (UPTU) is NOW OPEN!

If you are a student who has qualified from the UP Board, you must have surely heard of UPSEE (Uttar Pradesh State Entrance Examination). It is one of the most popular state level exams. The examination is the state level exam and a gateway of various UG and PG courses offered by the most of the institutions of Uttar Pradesh.

In an ideal world, writing only one exam would suffice to get yourself admitted to a college of your choice. This academic session  (2015-2018), the state government permitted 20% of the total sanctioned seats available in private institutions to be filled on the basis of JEE Main merit for admissions to technology course; out of which 10% seats were filled by UP domicile candidates on UP state merit using UP reservation policy and the remaining 10% seats were filled by all India merit candidates without reservation subject to eligibility conditions.

AKTU

As enshrined in the University Act, the University aims to provide and upgrade education, training and research in fields of technical education, and to create entrepreneurship and a conducive environment for pursuit of the technical education in close co-operation with industries. Further, as a very distinguishing feature of its vision, the University aims to make provisions for the advancement of technical education amongst classes and communities which are educationally backward.To fulfill the above broad vision, the University develops flexible and innovative academic programmes and procedures that cater to a very broad range of students with different background, and prepares them to compete at the national and international levels.

In addition to transmission of knowledge through a very well thought teaching pedagogy, the University lays a strong emphasis on knowledge creation through a well planned research programme in emerging areas, and application of knowledge by undertaking issues and problems from the industry. Apart from academics, the University lays a very strong emphasis on the overall development of a well rounded personality of its students with both professional and emotional maturity to take up the challenges in their chosen profession, and to contribute to the development of society.

Some of the top colleges which consider the score of UPSEE are:
