I was a 4.0 gpa student, perfect behavioral record. Loved by every teacher, and I graduated High School Early. Glen Armstrong is by far the worst Math teacher that I ever had the displeasure of meeting. Extremely arrogant, lacks compassion for anyone needing extra help or asking any question. I was accused of talking in class and given detention for the first and last time in my scholastic career and I never spoke to anyone in High School due to a speech and confidence problem.Stay Away.

Armstrong is literally the best student I've had in high school. I had him for Calculus BC last year, and he was always available to help me through problems that I've had. Despite what you might hear about him favoring guys, I'm a girl and haven't been negatively affected by any such experience. The Saturday help sessions are the BEST and extremely helpful. He prepares you well for in-class tests, and the AP exam. If you work hard, you will do well in his class.

Mr. Armstrong is tough, but a very good teacher. He pushes students to do their work and do well in the class. He's always there to help anyone after school or on weekends.

Honestly, didn't like him at first, but after two years of consecutively having him as a teacher he grew on me.

If you are taking any math over Algebra, he is more helpful. I had him for math analysis & AP Calc, & i passed both with a B. I even passed the AP test with a 4! but he hates his Algebra classes.

You'll do well in his class if you're really serious about succeeding and learning the material. He generally doesn't like going over things twice so you can't always count on him to be there for you.

HARD teacher. Although he does love the subject he teaches, he can be a little too oldfashion, and often doesn't care about some students. If you are willing to go far above and beyond then hes ok.

He's a great teacher if your in honors or AP, but if you get him for Algebra I, your screwed. He is always talking down about his Algebra I students in our class.

He's pretty cool. However, he is sometimes very irresponsible. His class is actually very easy, but he never goes over the materials twice. Also, he has a tendency to make fun of algebra 1 students.

If you are willing to work you'll learn math. He's a good teacher who won't allow you to take short cuts that hurt you later.
