Have the planners for 2 years now and am a big fan. Will I think no more substitutes. The color is not entirely mine, but there is also matching envelopes or you will even tinker active. The planner is particularly suitable for teachers who write down a lot. I always write me eg to controlling homework, the hours issue and the new homework in the column for the hour, so I do not forget anything. And you can all Vergesslistenmöglichkeiten thanks to the many columns back full advantage of the planners.
