Answer:
National standardized college entrance exams replace exams written independently by test administration services affiliated with groups of universities.
Step-by-step explanation:
Just like different states have different regulations for the issuance of drivers license, various test administration services affiliated with groups of universities have different standards for their test and admission procedure.
This standardised national test will ensure that admission across the country is based on one standardized examination rather than having different standards for different universities across the country leading to unreliability of test sores of several test administration services affiliated with groups of universities.
