How to improve PSAT in a month?

<p>Princeton review: first practice test is 31, currently take Princeton review ACT class.
No SAT or PSAT exam or class ever taken. Estimated current PSAT level is among 205 to 210. (Did free PSAT last week, result is not coming yet)
What is the best way and how to improve PSAT to among 210 - 213 (210 is last year's cutoff for MI)
Options:
1. PSAT classes, (only 3 sessions, 1st is practice test, another 6 hours for 2 session classes, 10/6/2011 and 10/10/2011, ends before PSAT test date, $300)
2. SAT classes: mostly ends until end of Nov, 2011. Will SAT class help PSAT more or PSAT class better in less than 30 days?
How about SAT liveOnLine?
3. Self-prepare: how about just lazy to do the practical test at home :)?
(BTW, I am the mom of the student. )</p>

<p>I would offer 2 matinee tix on a Sat or Sunday if my kid would do a practice test in the morning. Then kid and friend could go to a movie in the afternoon.</p>

<p>I will offer that too :)</p>
