in muay thai, wat should be covered over the period of 6 months?

That's hard to say because every school is different... at the academy I train at back home, the first 6 months covers alot of the basics. Proper boxing drills, how to round kick properly, clinch and knee, footwork and stances. Not too much else for the first 6 months there.

should be basics as damien suggests if they are a good trainer. they will also pay particular attention to your technique.

as in any martial art it should be the basics. These are the foundation or building blocks....and a building with out a good foundation will usually fall.......
