Has anyone gone to CCCCD McKinney or going there now?

They use a point system. you get points for how many pre-reqs you have completed and then you get points for your pre-req gpa, your overall gpa, and for how well you do on the PSB test. Look at their site and it will make more sense.

Make sure that you study for the PSB because these points can make the difference in getting accepted there - as long as your GPA is about the same. You will see the points for the gpa on the site.
Hope this helps!

Can you suggest any documents or books for PSB ?

When you register for the PSB they will give you a little packet of sample questions. I also used these two sites to study for the test.

From what I remember, the hardest part for me was the spelling. They had words that I would have never guessed were actually words. To get through it, I tried to go with what made the most sense.
Good luck to you!

I know some of their instructors. Definitely top notch all the way.
