"I'm quickly approaching 9 months of tutoring with Dr. Ruben and even with all that time to reflect upon his services I still lack the words with which to describe the sheer amount of knowledge and confidence I've gained through our time together. He and his work are nothing short of a miracle. For reference I’m a man who, at the begging of this endeavour, had not touched mathematics of any level for roughly 3-3.5 years. Ruben, without hesitation or pretence took me on despite the chasmic gap between where I was and where I wanted to be. And even though I've only made it through 1/4 of my journey, not even the first few steps would have been possible without this man. To say he is worth his weight in gold is an monstrous understatement, partially because he doesn't weigh that much, but mostly because he’s worth 5x that at least. I'm almost hesitant to post this because I think he’s one of Melbourne’s best-kept secrets (in terms of tutoring at least). 5/5 on all fronts, do yourself a favour and book this man."
