Preparing for Taekwondo Upgrading

Next Sunday I'm going for my Taekdondo 1st Dan to 2nd Dan senior upgrading. I am prepared? I also dono ler.... juz think it is the time to go for it.... I'm in 1st Dan for 3 years... so it is really have to go for it... really scare that i will forgot the Taegeuk, Koryo, 1-step sparring and self defense. But, the most i worry is my right leg... Now, i even cant kick a simple Front kick or turning kick with right leg.... my right knee is very painful T_T Standing is also a problem for me now.... My right leg is better than my left leg, so can i get good score with only left leg?? hopefully can lor.... Hope that i can get well soon la... if not really dono how to go grading... some more grading have to do swing kick, 360 turing kick, etc... Wish me all the best lor... ^_^
