★★★★★ Rated 5 stars by parents · Read reviews

Hi, I’m Tim.

I get it. It’s hard watching your kid struggle with math, especially when the homework doesn’t look like the math you learned.

Most students who struggle aren’t “bad at math.” Honestly, they’re usually missing one step, or it was only ever explained one way. So I explain it another way, with my own tricks and memory tools, until it clicks.

I studied Applied Mathematics at Rutgers and have tutored everything from elementary math to college Calculus and Physics.

My goal is steady progress every week, until your child feels confident on their own and doesn’t need me at all.

Not sure where your child should start? That’s pretty normal. Text me what’s going on in class, and I’ll suggest a plan.

What Parents Say

“Timothy was a great tutor for my son in both Honors Algebra and Honors Physics. He was kind, patient and efficient and helped my son understand the concepts. My son was very grateful for his help and his grades improved! Thanks to Timothy my son was able to remain on honor roll despite having two challenging classes. He was also available on text and Zoom. I highly recommend Timothy as a tutor for anyone looking for help.”
Kate S., parent (via Google)

“Timothy is an excellent Math tutor. He worked with my son during his junior year. My son struggled with his AP Pre Calculus class until he started working with Timothy. My son passed the year with an A. I would highly recommend Rusli Prep for help with any Math class or SAT review. Very professional, accommodating and kind.”
Donna N., parent (via Google)

“We are definitely very satisfied and happy with Timothy's classes. My son took pre calc last year and his grades improved. He is taking AP physics and AP calc this year and he is happy with the explanations and the attention. Both physics and calculus are difficult subjects for children and Timothy is well versed with the material and what is required for exam taking. I am totally satisfied and recommend him without hesitation to other parents.”
Badhuli S., parent (via Google)

“Tim is patient, encouraging, and creates a positive learning environment. His lessons are tailored to my child's needs and challenge my child. Since working with him, we have seen massive improvements in both grades and attitude toward school. We highly recommend Rusli Prep!”
Erica S., parent (via Google)

“We've had Tim tutoring our daughter since fourth grade, and now she's in fifth. The improvement we've seen, especially in math, has been amazing... I feel like she's slowly developing a genuine love for math, and that's not always easy to do. Tim also provides great updates after every session... He's thorough, dedicated, and genuinely invested in her progress.”
Omar, parent (via Google)

“As a parent, I've found it challenging to teach myself the 'new math' methods so I can help my children with their homework... Tim is incredibly personable, patient, and genuinely invested in helping his students succeed. My children actually look forward to their math sessions... He takes the time to review homework and test results, go over mistakes, and clear up any misunderstandings to make sure they truly understand the material.”
Tamar P., parent (via Google)

“I have been taking both my kids to Tim for the past 3 years. Tim is knowledgeable. He has great patience with kids and connects with them very well.”
Ram, parent of two (via Wyzant)

“Tim responded immediately to my request and made himself available for the next two days to tutor my son for his pre-calculus final. He is extremely professional and my son enjoyed working with him. My son received an A on his final exam.”
Desrie, parent (via Wyzant)

“He has been working with my son on SAT prep, physics and pre-calculus. As a B student with some learning challenges, my son needed a tutor that worked at a slower pace. Tim has done a great job helping my son prepare for tests while working at a good pace.”
Cynthia, parent (via Wyzant)

“Tim helped my son prepare for his SAT (in math). He was very professional, patient, clear, knowledgeable, and friendly. Most importantly, the rates were very reasonable in comparison to similar providers.”
Yvonne M., parent (via Facebook)

Frequently Asked Questions

Do you tutor online or in person?

Both. In-person sessions are at the Union Public Library on Morris Ave, and online sessions are over Zoom.

What grades and subjects do you cover?

Elementary through college: Math from basic facts through Calculus, high school and college Physics, and SAT/PSAT Math.

How long are sessions, and when are you available?

Sessions are usually 1 hour, and longer sessions can be arranged if needed. I’m available Monday through Saturday, afternoons and evenings, and morning sessions can sometimes be arranged. Feel free to text me any time, including mornings, and I’ll get back to you quickly.

What happens in the first session?

It’s an assessment: I find exactly where your student is strong and where the gaps are, and you leave with a clear plan for what we’ll work on. New students receive a free second session.

How do you keep students safe?

In-person sessions are always in a public place, the Union Public Library. For online sessions with younger students, a parent stays nearby. I schedule and communicate with parents directly rather than messaging students privately, and I never share or post student photos or information without a parent’s permission.

What should my child bring?

Recent homework, tests or class notes, a pencil, and a calculator for middle school and up.

How does payment work?

You can pay online by card through the secure links in the Rates section, or I can text you a payment link. Once-a-week and twice-a-week plans are prepaid each month at a lower rate per session.

What if we need to cancel?

Please give at least 24 hours’ notice to reschedule at no charge. Late cancellations and no-shows are charged in full.

Will I know how my child is doing?

Yes. I keep parents updated on what we covered and what to practice between sessions.
