That's great!
If you feel pretty good with your results and feel comfortable to move on to the next course, then go for it. Consistent Achievement will help to continue your success toward your goals and make sure you do so again and again. If you have a strong need to review parts of another course, then you can always go back at any time. I'd say, keep moving forward because there will always be a few things you can work on, and it sounds as if you are progressing wonderfully.
Keep up the great work!
