Taught by someone who's spent a career watching students get stuck in the exact same places.
Mr. Mohamed Abdallah holds a B.Sc. in Mathematics & Education from the Faculty of Education, Alexandria University, Egypt, and a Diploma in Math Education from the University of Maryland, Baltimore County (UMBC), USA, where he completed the Egyptian Mathematics and Science Teacher-Scholar Program. He is a Google Certified Educator and Microsoft Certified Innovator, holds a Saudi Teaching License in Mathematics with a 96% score, and in 2023 won Egypt's first Global Certificate in Mathematics competition for adults.
In 33+ years teaching mathematics — including as Head of Mathematics at Asia International School in Al Khobar and currently at Edugates International School in Jeddah — across Cambridge IGCSE/GCSE and AS/A-Level, AP Calculus AB/BC and AP Statistics, the Digital SAT and ACT, and the Saudi national exams GAT Qudrat and SAAT Tahsili, he has led curriculum design, teacher mentoring, and data-driven intervention programs that raised student achievement by 15%.
That breadth across curricula is the real asset: the algebra mistake that trips up a Digital SAT student is the same one that trips up an AP Calculus student a year later, and teaching every level at once makes those patterns hard to miss.
ClipSAT grew directly out of that classroom experience. Every explorer on this site exists because a verbal explanation of "the tangent line's slope approaches the derivative" wasn't landing — but dragging a point and watching it happen always did. The same philosophy shapes every track: read the idea in plain language, watch it move, practice it until it's automatic, then keep a clean copy for review before the exam.

What families say.
Mr. Mohamed Abdallah is an exceptional mathematics teacher who delivers outstanding results. Under his guidance, our students have achieved remarkable success: Omar, Salma, Noor, Yasmeen, Mohamed, and many more students scored a perfect 5 in AP Calculus AB/BC. Nadine, Yousf, Nour, Haya, and a long list of others earned A and A* grades in IGCSE Mathematics (AS and A2 levels). Mohamed and Shereen achieved an impressive 36 in ACT Math.
Mr. Mohamed's teaching style is clear, engaging, and highly effective. He breaks down complex topics like calculus, trigonometry, quadratics, and integrals into understandable concepts and provides excellent revision sheets, practice problems, and targeted exam strategies. His dedication and expertise helped our children not only master the material but also build confidence for top university placements.
We highly recommend Mr. Mohamed Abdallah for any student aiming for excellence in IGCSE, AP, or ACT mathematics. He is truly one of the best math tutors in Jeddah!

Three ideas, done properly.
Every chapter on ClipSAT follows this same shape — definition, theorem, proof, worked example — not just answers.
1 · The Fundamental Theorem of Calculus
A function \( F \) is an antiderivative of \( f \) on an interval if \( F'(x)=f(x) \) for every \( x \) in that interval.
If \( f \) is continuous on \( [a,b] \) and \( F \) is any antiderivative of \( f \), then \[ \int_a^b f(x)\,dx = F(b)-F(a). \]
Let \( G(x)=\int_a^x f(t)\,dt \). The theorem's first part (not restated here) gives \( G'(x)=f(x) \), so \( G \) is also an antiderivative of \( f \). Two antiderivatives of the same function differ by a constant, so \( F(x)=G(x)+C \) for some \( C \). Then \[ F(b)-F(a) = \big(G(b)+C\big)-\big(G(a)+C\big) = G(b)-G(a) = \int_a^b f(t)\,dt - \int_a^a f(t)\,dt = \int_a^b f(t)\,dt, \] since \( \int_a^a f(t)\,dt=0 \).
Evaluate \( \displaystyle\int_1^3 (3x^2-1)\,dx \). An antiderivative of \( 3x^2-1 \) is \( F(x)=x^3-x \). So the integral equals \[ F(3)-F(1) = (27-3)-(1-1) = 24-0 = 24. \]
This is exactly what the Riemann Sum explorer above is showing you converge to as \( n\to\infty \) — and \( F'(x)=f(x) \) is exactly the tangent-slope statement from the Derivative explorer, run in reverse.
2 · Completing the Square & the Quadratic Formula
For a real number \( p \), the trinomial \( x^2+2px+p^2 \) factors as \( (x+p)^2 \). "Completing the square" means adding the right constant to a quadratic expression so it takes this form.
For \( a\neq 0 \), the solutions of \( ax^2+bx+c=0 \) are \[ x = \frac{-b \pm \sqrt{b^2-4ac}}{2a}. \]
Divide by \( a \): \( x^2+\tfrac{b}{a}x+\tfrac{c}{a}=0 \), so \( x^2+\tfrac{b}{a}x=-\tfrac{c}{a} \). Add \( \left(\tfrac{b}{2a}\right)^2 \) to both sides to complete the square on the left: \[ x^2+\frac{b}{a}x+\left(\frac{b}{2a}\right)^2 = \left(\frac{b}{2a}\right)^2-\frac{c}{a}. \] The left side is \( \left(x+\tfrac{b}{2a}\right)^2 \); the right side simplifies to \( \tfrac{b^2-4ac}{4a^2} \). Taking square roots, \( x+\tfrac{b}{2a} = \pm\tfrac{\sqrt{b^2-4ac}}{2a} \), so \( x = \tfrac{-b\pm\sqrt{b^2-4ac}}{2a} \).
Solve \( 2x^2+8x-10=0 \) by completing the square. Divide by 2: \( x^2+4x-5=0 \Rightarrow x^2+4x=5 \). Add \( 2^2=4 \): \( x^2+4x+4=9 \Rightarrow (x+2)^2=9 \Rightarrow x+2=\pm3 \Rightarrow x=1 \) or \( x=-5 \).
The quantity under the root, \( b^2-4ac \), is the discriminant: positive gives two real roots, zero gives one repeated root, negative gives two complex roots.
3 · The Unit Circle & Exact Trigonometric Values
Let \( \theta \) be an angle measured counterclockwise from the positive \( x \)-axis, and let \( P=(x,y) \) be the point where its terminal side meets the unit circle \( x^2+y^2=1 \). Define \( \cos\theta = x \) and \( \sin\theta = y \).
For every angle \( \theta \), \[ \sin^2\theta + \cos^2\theta = 1. \]
By definition, \( P=(\cos\theta,\sin\theta) \) lies on the unit circle, which is exactly the set of points satisfying \( x^2+y^2=1 \). Substituting gives \( \cos^2\theta+\sin^2\theta=1 \).
Find the exact values of \( \sin\frac{\pi}{3} \) and \( \cos\frac{\pi}{3} \) (60°). A 30–60–90 triangle with hypotenuse 1 has legs \( \tfrac12 \) (opposite 30°) and \( \tfrac{\sqrt3}{2} \) (opposite 60°), so \( \cos\frac{\pi}{3}=\tfrac12 \) and \( \sin\frac{\pi}{3}=\tfrac{\sqrt3}{2} \). Check: \( \left(\tfrac12\right)^2+\left(\tfrac{\sqrt3}{2}\right)^2=\tfrac14+\tfrac34=1 \). ✓
Since adding a full turn returns \( P \) to the same point, \( \sin(\theta+2\pi)=\sin\theta \) and \( \cos(\theta+2\pi)=\cos\theta \) — both functions are periodic with period \( 2\pi \).
Take it with you.
