A lot of new puzzle types (probably all?) in this test. Many of you may not be familiar/comfortable with some of the puzzles, so below are some practise puzzles (apart from the puzzles in the IB) created by some of my puzzle friends.

It is worth trying out some of these puzzles, it would only help in you being better prepared for the test.
The No Numbers Loop looks like a tough one (especially considering its high points). Synchronized Maze and Trio Cut are my favourite of the set.
Good Luck to all participants!
