I think it was flat-out on page 1 of this thread who mentioned not getting F1s until you get all golds. 👍
But it would take some much fun away from the game at the same time since people like me, couldn't get super license gold until I came to the gtp and learned how to really race.
Now I can do all golds.

(have a pal gold on my ntsc s8... didn't want to be a slacker compared to the euros)
As for this test... s3.
I just ran this test again actually...
I took a few weeks off from gt3 and went back to socom, and that created a problem. I hadn't raced in a while, so I needed some practice.
In comes this thread.
I saw this thread and figured, what the hell! I need the practice and this test is a nice one to start with.
Well needless to say, I nailed the gold in a few tries.

But it was still a nice race to work on.
The bottom line for this race is to remember that keeping your speed up is key.
Also, since you're driving a stock-ish (don't really know) miata, you can't do un-needed down shifts running into redline.
Down shifting into 2nd on many of those turns is tempting, especially since the redlined engine sounds fast, however, the only spot you need to drop into second is the turn right after T1.
Other than that turn, 3rd will carry you through every turn, and do it faster.
Good luck and remember, run it over and over, and even use your ghost to find where you lost that precious time.
Also, remember my comments about 3rd gear and not dropping into second anywhere except the first turn after t1.
If you can keep all that in mind, you should be able to nail down a bronze without too much work.
Good luck.
Keeping your speed up + proper gear selection + ghost run & demo studies = victory. 👍
