Grade

Im doing Pearson BTEC Level 3 National Extended Diploma RQF (1080) (2016 to Present) in Applied Science
i got pass in unit 1 one mark off Merit
Unit 2 distinction
Unit 3 merit
Unit 4 distinction,unit 5 pass 16 marks, unit six still doing it but let's assume i got merit,unit 7 pass 18 mark, unit 8 distinction ,unit 10 distinction , unit 12 distinction ,unit 13distinction ,14 so far distinction in B and C ,unit 21 distinction will i be able to get DDD?

The way BTEC grades work is that each unit is awarded points depending on it size (in guided learning hours - GLH), your grade, and your mark in the case of external (examined) units. They then total the points and map it to an overall grade. So let's run through those units to see what each is worth in terms of points.
Unit 1: A pass in an 90 GLH external unit earns you between 9 and 14 points, depending on the mark. As you were "1 one mark off Merit" it'll be 14 points.
Unit 2: A distinction in a 90 GLH internal unit earns you 24 points.
Unit 3: A merit in a 120 GLH external unit earns you between 20 and 31 points. You provide no indication as to your mark, so let's assume 20 points.
Unit 4: A distinction in a 90 GLH internal unit earns you 24 points.
Unit 5: A pass in a 120 GLH external unit earns you between 12 and 19 points. You say "unit 5 pass 16 marks", which seems wrong given then in the minimum mark for a pass was 28 in June 2023 and January 2024 and was 34 back in January 2023. I'm therefore going to assume 12 marks (a bare minimum pass).
Unit 6: A merit in a 90 GLH internal unit earns you 15 points.
Unit 7: A pass in a 120 GLH external unit earns you between 12 and 19 points. You say "unit 7 pass 18 mark", which is was a little above the pass boundary in January 2023, June 2023 and January 2024. Without knowing when you took this exam, I can't be precise, but this means you'd have earned approximately 13 points.
Unit 8: A distinction in a 60 GLH internal unit earns you 16 points.
Unit 10: A distinction in a 60 GLH internal unit earns you 16 points.
Unit 12: A distinction in a 60 GLH internal unit earns you 16 points.
Unit 13: A distinction in a 60 GLH internal unit earns you 16 points.
Unit 14: An assumed distinction in a 60 GLH internal unit earns you 16 points.
Unit 21: A distinction in a 60 GLH internal unit earns you 16 points.
I make that total 218 points. For a DDD you need 216 points, so it looks like you've probably just made it.
Note, however, that there is some uncertainly. For more clarity could you please:
1. Provide a mark for Unit 3.
2. Provide the month and year when you took the Unit 3 exam (as the grade boundaries move around a little).
3. Double check your Unit 5 mark. You say "unit 5 pass 16 marks" but that doesn't align with any of the last three sets of grade boundaries.
4. Provide the month and year when you took the Unit 5 exam.
5. Provide the month and year when you took the Unit 7 exam.

So i took the exams for 3 ,5,7 this year 2024 / January i wasn't given my mark for unit 3 so let's just assume the lowest for merit
Unit 5 overall was 16 marks i got 12 in chemistry,14 biology and physics
Unit 7 also January 2024 I did resit unit 7 probably done much better

For Unit 3, I'd already assumed the lowest mark for which you could obtain a Merit - which earns you 20 points.
For Unit 5 I'm still confused by your "overall was 16 marks" comment, especially when you also say, you "got 12 in chemistry,14 biology and physics". The Unit 5 exam comprises three papers (Chemistry, Biology and Physics) worth 40 marks each, for a total of 120 marks. If you got 12/40, 14/40 and 14/40 that would be a total of 40/120 overall. Yet you say "overall was 16 marks". Perhaps you mean 16 points?
In January 2024 the Pass boundary for Unit 5 was 28 and the Merit boundary was 51 - i.e. a 23 mark difference. So your 40 was 12 / 23 of the way between the two boundaries. So your points would be 12 + (12/23 of the 8 point difference between a Pass and a Merit). That 16 points (rounded). Aha! So you did mean 16 points not 16 marks.
I'd assumed 12 points above, so we need to bump your overall points up by 4.
For Unit 7 you scored 18 out of 50. In January 2024 the Pass boundary was 16 and the Merit was boundary was 25. So you were two ninths (2 / 9) of the way to the Merit boundary. So you earn the Pass points (12) plus two ninths of the difference between the Pass and Merit points (20 - 12 = 8). So that's 14 points (rounded). I'd estimated 13 points above, so we need to bump your overall points up by 1.
Your overall points are therefore 223 - a more comfortable DDD.

Yes i got 40/120 in unit five not sure how many points so yh probably that 16 is the point not the mark,thanks alot for your help really make me feel much better 🩷

Hi in unit 1 I got a near pass and unit 5 I think I would get a near pass as well but I need 88 ucas points to get into a contextual offer at university. Please could you see if I will be able to get in?
Unit 1 NP-8
Unit 2- merit
Unit 3-pass 15
Unit 4-merit
Unit 5- NP not sure yet result in august
Unit 6-merit
Unit 7-let’s say pass don’t know yet
Unit 8-pass
Unit 10-pass
Unit 11-distinction
Unit 12-distinction
Unit 17-distinction
Unit 19-distinction

Which subject? Applied Science? (The size of each unit - and therefore its impact on your overall BTEC grade - isn't consistent between subjects.)

I’m doing applied science level 3 extended diploma.

In addition to the "standard" Applied Science, there are a few variants. From that list of units, it seems that you're doing Applied Science (Biomedical Science). Agreed? (Your list of units is actually allowed in the standard Applied Science.)
You say you need 88 UCAS points. The lowest grade you can achieve in your BTEC and still get at least 88 UCAS points is MMM, which earns you 96 UCAS points. Fortunately, even if we take a worst-case scenario for Unit 5 and Unit 7 (in green below), you still get MMM overall.

(Do please check that I've entered your other unit grades correctly.)

Yes you have entered everything correctly, this is a huge relief thank you very much. 😊
