Hi, Zhila.
You said "...I forgot some words "
If you want to change the grades of FORGOTTEN WORDS ONLY, here is the General idea:
Tag them and then Review the tagged cards only. You will have less cards to go over;
and do not have to delete the original cards.
If this approach is more appealing to you than 'wholesale' conversion, I can provide a Step-by-step verified process.
