Vietnam Japan University builds rules for converting scores between admission methods

Specifically: For the method of considering capacity documents and interviews, the principle of converting scores to a 30-point scale based on the percentile method between methods and combinations is as follows:

TT	High school score	Admission score based on profile and interview	Conversion formula
1	19.00-20.25	65-70	y = 0.25*x + 2.75
2	20.25-23.25	70-80	y = 0.3*x - 0.75
3	23.25-26.50	80-90	y = 0.325*x - 2.75
4	26.50-28.01	90-95	y = 0.3027*x - 0.7448
5	28.01-30.00	95-100	y = 0.39728*x - 9.7280

(x is the score of the application and interview, y is the score after converting to a 30-point scale).

* For the admission method of considering the results of the standardized SAT exam, the principle of converting scores to a 30-point scale based on the percentile method between methods and combinations is as follows:

TT	High school exam scores	SAT score	Conversion formula
1	22.98-23.62	1,100-1,160	y = 0.010739*x + 11.167484
2	23.62-24.50	1,160-1,250	y = 0.009735*x + 12.332011
3	24.50-25.35	1,250-1,340	y = 0.009442*x + 12.698357
4	25.35-26.03	1,340-1,430	y = 0.007514*x + 15.281653
5	26.03-30.00	1,430-1,600	y = 0.023374*x - 7.398190

(x is SAT score, y is score after converting to 30-point scale)

* For the admission method based on the results of the High School Aptitude Assessment (HSA) exam for high school students organized by VNU in 2025, the equivalent score according to the percentage ranking of HSA scores and A00 scores in 2025 is as follows:

Rank (%)	HSA	A00	Rank (%)	HSA	A00	Rank (%)	HSA	A00
100.00	130	30.00	89.49	97	26.75	16.86	64	18.50
