I did it! 81/100. After a year in CZ and doing the Beginners I class twice I think I can graduate to Beginners II now. Four out of seven cases and the past tense. Mind you I did completely flunk the oral Q badly and I think the teacher was very generous in the marking.
Three more cases, future and conditional tense to go and then start it all again for plural forms. It certainly helps with the Alzheimer’s.
