Body and Brain Connection

Cliff Notes - Use the XBOX Guide button to pause the game without time penalty.

Detailed Solution: In order to record a brainage of 20, you can't make any mistakes and you will need to answer quickly. Using the XBOX guide button allows you to instantly pause the game. This allows you time to determine the correct answer without wasting valuable time. You can even position your hands correctly while the game is paused.

However, this method is not perfect. It does not work for all games. Only 10 of the mini games are played during the brainage test. They are:

Which is Biggest?
Math jock
Balloon buster
What time is it?
Time bomb
Matchmaker
Flip and find
Traffic control
Mouse mayhem
Touch and go

Touch and go, mouse mayhem, traffic control and balloon buster can't be easily exploited by the XBOX guide button glitch.

I didn't even try Touch and go. I think this game is impossible If you have legitimately got A+ on this exercise, i would love to get some tips.

Mouse mayhem suffers from flaky controls. You will punch a mouse but it won't burst. I tried pausing and lining up the mice but i still missed them. *** EDIT - Dodgely points out that you can miss mice and still get a brainage of 20. ***

You can pause balloon buster to determine the correct order but you need to pop the balloons quickly. I scored a few 21's because of this game and it infuriated me. If you try this one, remember you have to be fast.

I didn't try pausing during Traffic control because i was able to beat this game without pausing. This game is not time based (as the cars come at regular intervals) so with some practice, you could ace this one.

The rest can be done easily using the XBOX guide button glitch. If i get a game you don't like, you can restart the entire test by selecting BACK -> QUIT TEST.

It felt like touch and go and mouse mayhem came up more often than random chance would suggest but stick to it and you will eventually get a favourable set of tests.

And, of course, you will need to do it 3 times to get the achievement.

If anyone has any thoughts on how to consistently beat Touch and go or mouse mayhem, let me know.

Good luck!

In addition to Johnny Skillz's brilliant solution, what you may want to know is that until you "stamp" the result, it is not recorded on your save-file. What this means is that if you don't get 20, you can always sign out and back in again - after the test result is displayed, but before you have stamped it - until you are successful, thus "cheating" the 1 attempt-per-day rule.

Obviously you will need to get a brain-age score of 20 3 times to get this achievement to pop.

Yes, I know that I don't have the achievement...yet, but I did not want this to get buried in the comments.
