Correct me if I am wrong

O.K. I have been playing guitar for about 5 years and am finally trying to teach myself music theory. So I have some questions on the minor scales. Please correct me if I am wrong, I dont want to start any bad habits.

a minor scale is made with the following:

I-II-IIIb-IV-V-VIb-VIIb-VIII

so that would make the folowing scales:

C Minor scale

C-D-Eb-F-G-Ab-Bb-C

G Minor Scale

G-A-Bb-C-D-Eb-F-G

D Minor Scale

D-E-F-G-A-Bb-C-D

A Minor Scale

A-B-C-D-E-F-G-A

E Minor Scale

E-F#-G-A-B-C-D-E

B Minor Scale

B-C#-D-E-F#-G-A

Hopefully Im right but if im not I would love some feedback! Thanks
