Btec grade calculator for uni

Hi, just wondering if someone can calculate my btec grades.
Im doing Pearson BTEC Level 3 National Extended Cert RQF in applied law and psychology and level 3 WJEC criminology. I need DDD to get into uni

Law
Unit 1: distinction
Unit 2: merit
Unit 3: distinction (predicted)
Unit 4: distinction
Psychology
Unit 1: distinction
Unit 2: merit
Unit 3: distinction (predicted)
Unit 4: distinction (predicted)
Criminology
Unit 1: C
Unit 2: B
Unit 3: (A or B) predicted
Unit 4: (A or B) predicted

Your tutor should be able to do this for you,
You can work it out yourself using the specification for Law and Psychology.
Law is; https://qualifications.pearson.com/content/dam/pdf/BTEC-Nationals/Applied-Law/2017/Specification/btec-l3-nat-ext-cert-in-applied-law-spec.pdf

Psychology is; https://qualifications.pearson.com/content/dam/pdf/BTEC-Nationals/applied-psychology/2017/specification-and-sample-assessments/btec-l3-nat-ext-cert-in-applied-psych-spec.pdf

Not sure how WJEC works as it is not a BTEC. The other issue is , is that not all Universities recognise it so you need to check that.
