Wow, this is a challenging text! I have some observations and recommendations:

1. Circles before and after straight lines (or between two lines in the same direction) are always written clockwise when they are the only strokes. So if you know how to write a circle after a m, n, t, or d, you should also know how to write it after sh, ch, or j: clockwise (paragraph 33 of your book). Hence the circles in Alger and interrogé are wrong.

2. The first r of sortir is omitted because -ort is written without the r (with the exception of the word sort, which is written right s – o hook – r).

3. Circles are always placed inside curves on their own (paragraph 32): so the e in santé is written inside the curve (you also missed the a of santé, which is placed outside the angle between the right s and the nt blend).

4. De ce should be phrased: d – left s.

5. Devant is written with the blend: def blend – a – n.

6. Journalistes neither has an a nor an r: j – oo hook – n – l – e – left s – t.

7. The o-hook retains its normal position in mot, so you don't need to turn it on the side because there isn't a horizontal straight line coming after.

8. The first e of Algériens is written inside the curve formed by the j and the r. So the first time you wrote it (as algérien) was correct.

9. Désespéraient is a doozy: d – right ses blend – p – e – r – e. The right ses blend is the one that starts with the right s.

10. de l'absence: d – l – a – b – right s – a – n – left s (always try to phrase de whenever you can).

11. accident: a – k – right s – e – d – a – n (paragraph 87)

12. vasculaire: v – a – right s – k – l – e – r (e is missing, and there is no oo hook)

13. The words cérébral and saluer are written with the left s (paragraph 86).

14. longement is written with the men blend, not the m (l – o hook – ng – men blend).

15. de son should be phrased: d – right s – n

16. The first o hook of homologue should be turned to the side, because it occurs before an n or an m (paragraph 12).

17. The word liens is correct.

18. dirigeants: d – r – e – j – a – n (the first e is omitted).

19. encore: a – nk – o hook – r (we use the nk stroke, instead of writing n and k separately)

20. I would phrase en fonction.

21. cinquième: 5 – over e circle (as if you were writing 5 degrees in longhand)

22. Since public is a brief form (p – b), then République is just r – p – b.

The majority of the mistakes I'm seeing is in how to connect the different strokes (in particular, consonants to circle vowels). To correct this, you should be writing the words and the practice material of each lesson in a notebook, sounding out each character as you write it, so that your brain gets used to the way the Gregg Shorthand characters are supposed to be joined. After you write, you should read it back so that you know that you learned the lesson. I know that the material of the book is awfully boring and that this can be a tedious exercise, but you will not be able to write any text whatsoever if you're second guessing how characters should be joined, as that's an integral part of the system. Your overall goal now, in addition to learning the theory, is to recognize how the different characters of the Gregg Shorthand alphabet are supposed to be connected to each other. If you do copy the lesson and read it back and do it steadily, you'll improve, trust me.
