Anoop George CSP

HSE Manager at Manweir WLL

I am incredibly grateful to Vishnu Sir for achieving the CSP (Golden Certification in Safety) in my 1st attempt (03 Months preparations).

The CSP-10th edition domains are very vast in modules which is quite tough to digest the theory concepts + maths if you are preparing alone since the real exam is fully concept based questions, instead of direct ones.

@ Zealosh, I could see a mentor who is delivering sessions with very passionate & with the pre-determined intention of all his batch students who shall be cleared exams @ their 1st attempt. Each session was developed in such a way that it will be totally an engageable sessions.

His delivery was sharp & focussed, he will be the real deal for your CSP success. His exceptional training delivery pattern is truly commendable as he makes the complex topics become easier by providing real workplace scenarios.

I highly recommend my HSE colleagues to choose Zealosh Academy for your CSP Exam.

Dr. Sachin Damle

Manager HSE, Mumbai Refinery at Bharat Petroleum Corporation Limited

The CSP syllabus is vast, covering diverse domains such as health, nuclear safety, biosciences, hygiene, industrial safety, environmental sustainability, training methodologies, classical management theories, behavioral and psychological theories, and disaster management. Since CSP follows the U.S. safety system, professionals from different backgrounds may struggle due to their exposure to mixed safety systems from various countries and organizations.

Without proper mentorship, candidates risk focusing only on familiar subject areas, leaving critical topics untouched. This gap in preparation can ultimately lead to exam failure. A mentor ensures comprehensive syllabus coverage, structured guidance, and a strategic approach to mastering all subject areas.

I highly recommend Mr. Vishnu Rajendran as an outstanding safety trainer for CSP/ASP certification. His in-depth knowledge, structured approach, and engaging teaching style make complex safety concepts easy to understand. His dedication to student success extends beyond training sessions, offering continuous support, motivation, and guidance. Thanks to his expertise, many professionals, including myself, have successfully achieved certification.

Pradheesh Premdas

Project OSH Engineer at National Project Construction

I would strongly recommend Mr. Vishnu Rajendran as the top choice for anyone pursuing CSP studies. His dedication, structured approach, and consistent follow-ups make him an exceptional mentor in this field.

In my personal experience, I received my TSP in 2020 and initially enrolled in classes at another institute, which I prefer not to name. Unfortunately, within just three sessions, I quit as I found the teaching method unengaging and difficult to understand. At that point, CSP felt like an insurmountable challenge—a mountain I believed I couldn’t climb.

Fast forward to 2024, when I approached Mr. Vishnu for guidance. From the very first session, his teaching style stood out as clear, engaging, and methodical. I found the classes extremely interesting and, for the first time, felt motivated to keep going. Over the course of 14-15 sessions, I never experienced a single moment of boredom. His routine assignments before each class and his diligent follow-ups kept me on track and progressively built my confidence.

Thanks to Mr. Vishnu’s guidance, I achieved my CSP certification with ease, and I’m proud to say I was the first in my batch to pass. His ability to break down complex topics into understandable concepts and his genuine investment in his students’ success are truly remarkable.

Mr. Vishnu not only sets a high standard in CSP training but also inspires his students to excel beyond their perceived limits. I wholeheartedly recommend him to anyone aspiring to clear the CSP.

It's my pleasure to write a recommendation to Mr. Vishnu Rajendran, founder of the Zealosh Training and Consultants. I enrolled in 21 Jan 2024 at Zealosh for the CSP (Certified Safety Professional) certification course and have the opportunity to learn on a golden platform of learning.
During the period of my learning from Mr. Vishnu, I have found him multi-talented in the domain of HSE qualifications. His class start-up punctuality, maintaining discipline, honoring each trainee for asking questions without hesitation and delivery of training materials along with associated queries were overwhelming!
Mr. Vishnu had played a vital role in building a strong confidence within me after reviewing my CSP exam preparations and wisely recommended writing the exam without further delay. I can’t express the happiness of that day (7th May 2024) when I achieved the CSP certification under his mentoring services.

I personally recommend HSE professionals who are willing to obtain CSP certification that Zealosh would be the right decision to get the necessary training and proper exam preparation with good results of course.

Thank you

I am happy to share that I have passed the CSP examination on my first try. For me, it was not a smooth journey to finish CSP examination easily. I had to manage Indian VISA and travel to India for this exam as there is no Pearson Professional Testing Centre in my country. The man who continuously supported and guided me with the best possible solutions is Mr. Vishnu Rajendran. From the very beginning of my CSP preparation I was connected to him and later I was admitted one of his CSP preparation daily training batches. The best part of his training session is, he is very much capable of identifying the gaps in each student and provide solutions accordingly. His training sessions are not like typical lecture type. During discussion of any topics, Mr. Vishnu always goes deep to make the concept clear with relevant examples and takes feedback from all the trainees. Trainees can ask questions and interrupt his lectures any time if they have any doubts and it is well acknowledged by him. For CSP preparation, he covers all the domains and provide sufficient training and practice materials to the students which are very much helpful to gather knowledge about the topics. Besides this, he conducts mock CSP examinations to make students familiarized with the real time CSP exam screen. For those who want to start your CSP preparation, I highly recommend having your mentorship with Mr. Vishnu. I wish all the best and success in every step of his journey. Thank You.

Muhammed Shah CSP, CertIOSH, IDip NEBOSH

Assistant Manager at RITES Ltd

For me, it was a sudden decision to prepare for CSP. It was not according to any planned target. The reason behind for such a decision was a LinkedIn post by someone that was thanking Mr. Vishnu for his guidance for that person to achieve CSP. Even before that, I had seen many LinkedIn posts by candidates thanking and appreciating him for his teaching skills. Thus, I became very excited to know about the method of his teaching and after seeing the LinkedIn posts about the guidance given by him to the CSP candidates, I thought of preparing for CSP under his guidance and approached him. He was very much approachable and he detailed all about CSP right from the stage of giving its application to BCSP. I had started my CSP preparations through him with limited time due to my busy work schedule. Even though I didn't have enough time for detailed preparation of the exam, his weekly classes helped me to build a strong base to know the contents on different domains and also helped to me to learn the tricks to get into the answers of each questions. He was very much responsive for all my queries and his motivations had driven me to achieve CSP. Upon my experience, Mr. Vishnu will be a right choice for those who are in need of guidance on CSP

I am a person who hates numbers and feel instantly nervous as I see any calculations - with this fear, I contacted Vishnu Rajendran to guide me on CSP preparation. Vishnu first took away my fears and then made me understand the logical way of tackling math problems. I felt so comfortable, such that I could handle all 20 math questions I got in my exam....I am in awe of his teaching skills. I am extremely grateful for his mentoring and guidance to achieve the CSP qualification.
