For a newbie, no custom clubs IMO. You'll easily make Pro, advance to the thirties' levels and eventually need a club or two then, see other post.
Enter tournaments, there may be an age issue, and there may be a country issue. Check the indications in your account section and ask WGT directly by mail in case of further trouble.
A secret...
IMO there are a few:
1) Get used to the different forms of shots, punch, pitch, flop, chip. Each of them has its own qualities. The program frequently offers the wrong shot (e.g. chip) which will not advance the ball sufficiently on other surfaces than green & fringe.
2) Try to hit full strokes, not less than 85 %. Below, strokes (except putter strokes) get
inconsistent concerning length & direction. Use the punch to get
further nominal distances.
3) Think math when putting. Rule of proportion applies by 100 %. Length is dependent on the green speed and elevation. Standard greens have the nominal lengths, the others are longer or shorter in env. 10% steps (3 feet each for the 30' starter putter scale). Elevation adds and substracts to the length linerally, about one feet length per inch elevation dependent on green speed. Use the frational indications by club movement during shot pull-up.
4) Use the (back)spin. It works even with starter equipment, but don't expect too much. More spin is for sale in the pro shop via clubs & balls.
