AI, Machine Learning & Data Science | MSc Artificial Intelligence and Machine Learning | Python, scikit-learn, TensorFlow | Applied & Business

I had been studying for the GMAT for nearly four months and was stuck at 610. Arush ran a proper diagnostic in our first session and worked out that my issue was actually data insights and timing, not the content. We rebuilt my approach over about three months focusing on quant pacing and DI patterns. The thing that worked was how he kept adjusting the plan based on my mocks rather than sticking to a fixed syllabus. Scored 725 and got accepted at my target school. Would recommend.

Quick one-off session to fix a broken Excel model at work. Arush diagnosed the issue, explained why it had gone wrong, and rebuilt the affected sections in about 40 minutes. Highly recommend.

Needed to get up to speed with INDEX MATCH and nested IFs for a marketing analyst role. Arush kept the sessions practical and used datasets similar to what I would actually be working with day to day. Felt much more confident going into the job.

Had sessions on data analytics covering Excel, SQL basics, and some Tableau. Arush was clear and systematic. A good choice if you are starting out in data and want someone who can bridge across the different tools.

Good tutor for SQL. Helped me get what I needed for job interview prep.

Great sessions. Very patient and practical. Particularly good on VLOOKUP and conditional formatting. Would book again.

I needed help understanding machine learning concepts for my data science module at university. Arush explained supervised and unsupervised learning clearly and we worked through a real classification example in Python. Made the topic much less intimidating.

I came to Arush wanting to move from basic Python into machine learning. He put together a very logical progression, from data cleaning and exploration, through to building classification and regression models with scikit-learn. What I really liked was that he always explained what the code was doing and why, rather than just giving me a template to copy. By the end of our sessions I was able to build and evaluate models independently. Would highly recommend for anyone serious about learning ML properly.

Had sessions on AI and machine learning with Arush for a work project involving predictive modelling. He is good at explaining the intuition behind algorithms without getting lost in the maths. Practical and focused.

I was switching into data analytics and needed to get my SQL to a professional level fast. Arush put together focused sessions with real dataset examples. His own experience with data in a consulting environment was evident in the kinds of queries he taught me and not just academic exercises. Helped me land a data role.

Took SQL lessons with Arush over about four sessions. Started from the very basics and worked up to joins and subqueries. He is good at building understanding rather than just showing you syntax - always explains what the query is actually doing. Good pace.

Used Arush for Excel financial modelling help for my business school coursework. He is strong on both the Excel side and the underlying financial concepts which made the sessions doubly useful. Recommend for MBA students working on finance modules.

Helped me pass my university database module. Very clear, patient, and tutored at a pace that worked for me.

Took sessions with Arush on both GMAT quant and Excel for different reasons but he handled both equally well. GMAT sessions helped me push past a plateau and Excel helped me with a work project at the same time. Good tutor who clearly has broad skills.

Had sessions covering both excel and corporate finance. Arush explains the financial concepts well and then shows how to apply them directly in Excel which is a much better way to learn than going through them separately. Practical and thorough.

Very helpful for my accounting coursework. Explained financial statements and ratio analysis clearly. Would definitely recommend.

Good finance tutor. Helped me with management accounting concepts I had been confused about all term. Clear and to the point.

I was self-studying for the GMAT and hit a plateau at around 660. A colleague recommended Arush and it made a significant difference. He quickly identified what was holding back my score and addressed it methodically. Sessions are structured but not rigid. Would recommend for anyone who has been self-studying but needs a push.

Strongly recommended.
Had sessions on deep learning with Arush as a refresher before starting a new project. He has a good grasp of the fundamentals - neural network architectures, backpropagation, CNNs. Practical and efficient sessions.

I got help from Arush on GMAT prep and also separately for some Excel work. Very adaptable - the GMAT sessions were strategic and analytical while the Excel sessions were very hands-on. Both were useful. Happy to recommend.

Really good GMAT tutor. Clear explanations, responds quickly, and genuinely helps you understand the logic behind the questions rather than just memorising formulas. Got the score I needed.

Good ML tutor. Helped me with my neural network assignment and explained the architecture clearly. Responsive and knowledgeable.

I had my corporate finance exam in three days and was in full panic mode. Found Arush online and booked immediately. He spent the first session diagnosing what I had misunderstood and the next two rebuilding from there. What stood out was how he made abstract concepts concrete - NPV, IRR, capital structure all made sense in a way they had not from lectures. Went into the exam feeling properly prepared. Highly recommend for anyone who needs focused, fast help.

Came to Arush wanting to learn both Excel and SQL for a data analyst role I was applying for. He was comfortable with both and helped me see how the two tools complement each other. Good teaching style - clear and patient.

Arush helped me understand data analysis concepts that my university lecturer had not explained well. Clear and concise. Passed my module comfortably.

Used Arush for Power BI and data visualisation support for a work project. He understood what I was trying to achieve and helped me build exactly what I needed. More efficient than I expected - covered a lot in two sessions.

I needed to upskill on Power Query and Power Pivot for a new role. Arush had good hands-on knowledge of both. Sessions were efficient and he tailored the content to my specific to my requirements and dateset rather than running generic examples. It was really helpful.

Arush saved my dissertation deadline. I was trying to clean and analyse survey data in Excel and was completely lost. He was available online within a day and walked me through pivot tables and data validation step by step. More importantly he made sure I understood what I was doing so I could finish the rest myself. Brilliant.

Took GMAT lessons with Arush while working full time. He was flexible with scheduling and made sure each session was focused and efficient. Particularly helpful for the verbal section - he gave me a framework for reading comprehension that I found very useful. Recommend for working professionals preparing for MBA applications.

I had tried two other tutors before Arush and neither were right for me. Arush is different because he actually took the GMAT himself at a very high level and understands the test as a student, not just a teacher. He helped me with quant and verbal over about six weeks and was very adaptable based on how I was progressing. I also appreciated that he was direct about what I needed to work on rather than just being encouraging. Scored 730 and I am genuinely grateful.

Booked Arush for GMAT prep around four months before my exam. He is good at getting to the point - no fluff, just practical strategies. The critical reasoning technique he taught me completely changed how I was approaching those questions. Ended up with a 690 which was well above my target.

Arush is a great GMAT tutor. He scored 760 himself so he actually knows the exam from the inside, not just from teaching material. My verbal score improved a lot after just three sessions. Happy with the experience.

I was transitioning into a data science role from a more traditional analytics background and needed to build my ML skills quickly. Arush was very good at helping me prioritise what to learn first and connecting it to the kinds of problems I would encounter in interviews and on the job. Sessions covered Python, scikit-learn, and we also touched on basic NLP. Efficient, practical and genuinely useful. Would recommend to anyone making the shift into data science.

Had sessions for CFA prep on the quantitative methods section. Structured and clear. Helped me feel much more confident going in.

Sessions on corporate finance for my MBA module. Arush is patient, explains well and knows his material. Valuation topics especially were well covered. Would use again.

I was scoring around 640 on practice tests and was not sure how to break through to 700+. Arush helped me identify exactly where I was losing marks and put together a very focused plan. His explanations of GMAT quant, especially data sufficiency, are genuinely some of the best I have come across. Went on to score 710 and got my first-choice MBA offer. Would highly recommend.

Arush is a great tutor and he had a lot of patience with me. In just 5 sessions, I started to feel super confident with the functionalities and functions of Excel and this really came in handy in my new job.

I was taught data analysis by Mr. Arush and he was really good at it. I enjoyed my classes and the concepts were very clear. His way of teaching was very systematic and that helped me learn faster and better.

I would recommend Arush because I have myself learned SQL with the help and guidance of him. He explained every concept in a good manner and cleared all my doubts.

Arush was very thorough and helped me understand concepts that are essential for having a good grasp in Data analysis. I liked how he was concise and to the point. His approach helped me a lot.

I have been learning data analysis from Arush this summer and it has been a great experience. He is a very thoughtful teacher who puts a lot of thought into how he presents the material. His lessons were engaging, useful, and he was very patient with everyone in class always encouraging his students to try. I would highly recommend him to anyone interested in learning data analysis.
