Help with calculating overall BTEC grade

Hello, I’ve currently finished my BTEC extended diploma in art and design and I received the grades from my teacher. They were all passes.
This last unit was worth 50% of the grade.
I have done 4 units
The first unit I got distinction
The second I got merit
The third I got merit
This last one I got pass
Could someone calculate what my overall grade would be?
The unis I applied to want mainly DMM

There are 13 units in the Extended Diploma and if you have just done the first year, you should have covered more than four by now. Also the grades vary between Eternal and Internal; and by GLH so you need to give more information (ie what units numbers and grades and what actual mark (points) for any exams).
You can calculate it yourself by using the information and tables in the specification; https://qualifications.pearson.com/content/dam/pdf/BTEC-Nationals/Art-and-Design/2016/specification-and-sample-assessments/btec-l3-nat-ext-dip-in-art-and-design-spec.pdf

could you help with mine
unit 1: P
unit 2: M
unit 3: P
unit 4: P
unit 8: D
unit 15: P
unit 9: P
unit 12: M
unit 21: M
unit 6: D
unit 13: P/M I don't know yet
unit 7: Didn't get second results but I got pass
unit 5: I got a near pass but redid it so I don't have results again
i did applied science and want to do a foundation year i need a MMP

Are you doing a straight BTEC Applied Science and are are those unit numbers correct? You need to complete at least one init from Group B, which are 14, 19, 22, 23, 25 or 26. See Pages https://qualifications.pearson.com/content/dam/pdf/BTEC-Nationals/Applied-Science/2016/specification-and-sample-assessments/BTEC-L3-Nat-ExtDip-in-Applied-Science-Spec.pdf
or are you doing Applied Science (Biomedical) option?
If so you have an MMP overall;

I didn’t do those units only the ones I listed and I’m doing betec applied science extended diploma. I failed unit 5,7 so I resat them but before I got unit5: near pass and unit7: pass. I also got unit 13: M

In which case you will better check with your teacher ASAP. If you don't complete the correct units from each Group then you will not receive a qualification (just Unit certifications). If you are doing the straight Extended Diploma in Applied Science then 'You need to complete at least one unit from Group B, which are 14, 19, 22, 23, 25 or 26.

I’m scared now. Can you message me please

Look at the link I put in my earlier post #4. You will see that Pages 12 and 13 of the specification state that you MUST complete six optional units. The optional units are grouped. Learners must take 1–3 units from group A, 1–3 units from units group B and 1–3 units from units group C. The list you have given does not include any from Group B so that is a concern.
That's why you need to check with the teacher . As I also said they may have registered you for the Ext Dip in Applied Science (Biomedical) option Pages 14 to 15 of spec, in which case you have an overall MMP.
@DataVenia for info.
