Our students love us
He really taught me everything I could know about accounting. The way he explains things just makes sense and for the first time, I actually felt like I could get a handle on everything.
Lea D.
Mike helped me achieve amazing grades in all my accounting classes. His teaching style helps students actually understand the material being taught. He will not stop until you fully understand the concept. He is very approachable when you have questions. All his material gets you super prepared for your midterms and finals.

If it wasn't for Mike I would've never been able to get through my business and math classes. I ended every class he taught me with an A and he made the learning process so interesting and enjoyable. I definitely recommend him!

Claudia pays attention to detail, making sure that I understand every aspect of the material. She approaches problems from different angles, making complicated concepts much more manageable. She is always ready to help! I cannot recommend someone better.

When should I start preparing for COMM 214’s midterms and final exam?
Start with weekly tutorials from Week 1 to stay on pace with the material — stats concepts build on each other.

COMM 214 grading usually includes midterm and a final exam, with possible homework assignments or participation marks. Most questions are computational and require clear setups (formulas) as well as interpretation of results.
What kind of exam practice do you provide for COMM 214?
You’ll get mock midterms and final exam practice based on real past exams, covering descriptive statistics, probability, confidence intervals, and hypothesis testing. Each solution is fully explained so you know not just what the answer is, but why.
Which statistical tools are emphasized in COMM 214?
You’ll use tools such as Excel, MegaStat, or StatCrunch to calculate descriptive stats, probabilities, regression outputs, and hypothesis tests — learning both manual calculation and computer-assisted analysis.
