These are the elements specific to these particular forms. You also need to cover all the elements listed in the "Taeguek Cheat Sheet".
Taeguek Ee Jang
1. Your high high punch is about to nose level.
2. On the last leg of the form you must pivot when doing the kick but on the rechamber and set down your heel should come straight back into a walk stance.
Taeguek Sah Jang
1. Your press should be at a 90 degree angle from your body and your poke (spear hand) should have a slight downward angle.
2. Chamber for the high block and a knife (serve it up) and land the timing in the front stance.
3. Outside block stays within your body triangle – it shouldn’t extend past your side or extend the shoulder joint.
Taeguek Yuk Jang

2. Accurate chambering on the last leg – chamber/press/punch, chamber/press/punch.
3. The “press” is a board break in front of you – it should be level and a bit higher than your belly button. Palm is flat and hand is in a knife.
