POSSIBLE HOW TO's . . .
1. Apply now to attend a summer officiating camp where you can get immersed intensely in 3 man mechanics over the course of a weekend. Then work on what you will have learned there in the subsequent season. Then go again the next year.
2. Volunteer your participation for as many pre-season frosh, jv, and varsity scrimmages as your area offers where they might be workshopping 3 man mechanics in preparation for the season to come. Even if there's no pay, the value you derive may be worth it.
3. Don't watch NCAA or NBA on television with the intent of picking up tips on 3 man mechanics. The differences between those and the Fed mechanics are enough to really screw you up. Especially NBA. Plus the partial glimpse of only one or two officials on the tube doesn't really contribute to an awareness and appreciation of the flow of all three together. Rather. . .
4. Go to games on your off nights and observe 3 man crews in action. Have your NFHS Officials' Manual with you. Take actual notes and review them at home. Ask your assignor where some really good officials are scheduled and learn from them.

Just some misc. ideas. I'm confident others will have more valuable suggestions for you.
