I passed American Sign Language level 4 and Math.. Now that it's summer time I feel like all I have learned in such a short time is slipping away. Sad but true.... How do you retain such vast knowledge? And can anyone help me with my ASL grammar? I am signing so much English and I do not have a full grasp of the grammar and syntex. I feel like I was thrown a bunch of just stuff and don't know how to use it.... Can someone help?
