What is the best way to increase my IQ score in 365 days? ?

Technically, your IQ can't be increased, only decreased. It's supposed to be a measurement of your innate ability. However, since there's no good way to measure that, you can increase your score on IQ tests even if you're not actually becoming more intelligent. The best way to do this is by increasing your vocabulary (reading more) and practicing logic puzzles.

The only sure fire way of increasing your IQ score is to practice lots of rubbishy IQ tests online, because the proper tests use the same template of questions. But bare in mind this is cheating and that you are not actually increasing your IQ.

First, one must acquire the knowledge that 365 days = 1 year.

I would say read challenging books by authors like Shakespeare and practice algebra, geometry, and trigonometry skills (if possible).
