We recently wrote about MathCrunch’s offer of a free month of math tutoring. Exciting news: they’ve launched Chemistry and Physics on Android! And even better, until April 3rd, 2016 – it’s completely free.

To get free tutoring, download MathCrunch on Android with promo code Samantha476 and enter a payment method. Don’t worry, you won’t be charged for Chemistry or Physics and your first hour of math tutoring is free!

And remember – All MathCrunch tutors attend or are graduates from top universities. Every tutor is a subject-matter expert, and has a passion for helping students learn.

What subject do you have the most difficulty in?
