Welcome to HappyPrep! Can we be hardcore about test prep while also having fun? Of course! What could be better on a Saturday night than determining the sum of the diagonals of the faces of a cube with a volume of 125 (30 root 2), or memorizing the meaning of the word "sesquipedalian" (given to using long words)?

HappyPrep is the brainchild of Jennifer Dziura, an Ivy League graduate and holder of perfect SAT and GRE scores (and a 780 on the GMAT).

Jennifer has taught and tutored over 2,000 students and written and edited portions of test prep books available at Barnes and Noble. She has taught for major national test prep companies, in public and private schools, and for an intensive Korean hagwon. She has over a decade of experience helping students succeed (without stressing out too much).

I am so happy with these scores and I owed a lot of it to you, again thank you so much. You were a great help! Thanks again!

Junior, Greenwich High School

I just looked at my scores from the October SATs and I can't believe it!! I got a 740 / 680 / 750 and a 12 on my essay for a total of 2170!!! At the beginning of the summer I never imagined I could achieve a score like this, thank you so much for everything, I could not have done it without you!"

Senior, United Nations International School

"I want to thank you a billion times over for tutoring me for the SAT I last year because I'm sure it helped me in the college admission process and it made me much less of an inefficient, thick-headed person...I got into Cornell, Brown, Dartmouth, UPenn, Williams, Georgetown, UChicago, NYU Honors and a few others. As of now I am officially a Dartmouth '13! I just sent in my letter of intent last week."

Great Neck South High School graduate, now a freshman at Dartmouth

"Jennifer Dziura first tutored me for the SHSAT (NYC's specialized high school admission test) when I was in 9th grade, and had decided to go to a different school for my sophomore year. After a tutoring session with her, I went into the test feeling calm and secure, and I was able to gain admission to Stuyvesant, my top choice, even though only approximately thirty students could be admitted into the class in sophomore year. Several years later, I decided I wanted tutoring to prepare for the SAT, and I went straight to Jennifer. With her help, I was able to bring up my score significantly. My PSATs score provided a projection of a 2200 score on my SAT, as did my early practice tests. When I took the SATs after several months of tutoring, I received a 2330, with an 760 in Writing, a 770 in Math, and an 800 in Critical Reading. Jennifer Dziura is an excellent tutor. With both an excellent understanding of all the strategies, tricks, and concepts involved throughout the SATs, and a brilliance in explaining them, she is able to masterfully prepare students for anything that may appear on the SAT exam."

Comments from middle school students Jennifer has tutored:

"Thank you SO much for tutoring me all these weeks for the TACHS. A lot of the material we worked on was on the test, and I got it done really quickly. It turns out that the tutoring sessions that I took at my school didn't really help. So I'm really glad you helped me, thank you again."

8th grader, Epiphany School

Comments from Jennifer's students at Manhattan GMAT:

"Ideas are awesome. Speed math is engaging. Very structured and organized explanations."

" Jennifer keeps you on your toes. She starts the class explaining how you have to think really fast on the GMAT and how she will speak really fast to keep us in that mindset and she's not kidding! This is great because she's just very inspiring and challenging but at the same time provides great explanations and makes sure everyone leaves the class understanding the answers and the process/strategies to get to them."

" She's very enthusiastic and smart. She can make up alternative examples really easily, which is helpful when the standard answer/question is confusing. I also like that she would email us outside of class with tips/reminders."

" Jennifer is extremely lively, which is important in a 3 hour class. She also makes sure that everyone understands the answers before moving on; you almost feel like you're receiving individual tutoring."

"When I'm terrified on planes (i.e. always) I look to flight attendents who seem calm. When I am terrified during math section (i.e. always) I look to Jen who's relaxed, jovial, unburdened by intimidating problems."

" One of the best teachers (in any subject at any level) I've had."
