Hi... The only way to remember the new vocabulary is to practice again and again... Good luck!

Learning a different language takes time and motivation, you would have to speak it every day constantly in order for it to stick (in ur head longer)

Don't tire yourself with counting "that's right Blitzy who does it?! :) ". They can't be ever kept in your mind forever unless u keep reading & using them in your daily life.
