Seems to be reasonable enough. I will stop all non-tactic solving activities for a while (playing, etc..) so I can concentrate on finishing the program. Usually I do reviews of the problems I miss, but I will stop that also. If I miss a problem, then I miss a problem. Nothing to do anymore there.
Caveat:
To fit the plan inside the month of May, I did not solve about 20-30 odd problems whose solution goes 10+ moves deep. Trying to solve one of them consumes about 30min to 1 hour. But I feel I dont get anything anyway, except as a sort of calculation exercise. So I just crossed them out.
Congrats! Go ahead. Good luck!
