that is impressive. i have also started my preparation for CSS 2019 but in some groups on fb some people who have managed to clear this exam suggest you should study at least 18 hours out of which 6 hours should be writing practice. and that is supposed to make you feel like you can not do it. that is just first month of preparation and i have covered 3 subjects IR, GS, ISL but i feel like no i'm not going to pass it
