Common Questions
Frequently Asked Questions
Everything you need to know before enrolling. Can't find your answer? Call +91 98840 92863
What is the duration of the Data Science course at Cognitec?
The Data Science course is 6 months long with 120+ hours of classroom instruction. You can choose weekday morning (Mon-Fri 9-12), weekday evening (Mon-Fri 6:30-9), or weekend (Sat-Sun 10-2) batches depending on your schedule.
What are the Data Science course fees and are EMI options available?
The course fee is ₹70,000 (all-inclusive) covering all course materials, certifications, and placement assistance. EMI options start from ₹5,833/month through our financing partners. We also accept full upfront payment with a 5% discount. Call our counsellor for the exact plan that works for you.
Who should enroll in this Data Science and AI course?
This course is ideal for: working professionals looking to transition into Data Science/AI roles, fresh graduates from BE/B.Tech/BSc/BCA/MCA/MBA backgrounds, career switchers from non-tech fields, and college students wanting to build job-ready skills. No prior coding experience is required.
Is this an online or classroom-based Data Science course?
Our Data Science course is 100% classroom-based at our physical centers in Chennai (Anna Nagar, Padi, Velachery) and Coimbatore. We do not offer pre-recorded videos or online-only sessions. In-person learning with direct trainer interaction delivers significantly better outcomes than self-paced online courses.
What is covered in the Data Science Machine Learning curriculum?
Our curriculum covers the full Data Science Machine Learning lifecycle: Python programming, SQL & databases, statistics & probability, data analytics with Pandas/NumPy, data visualization (Tableau, Power BI), Machine Learning (supervised, unsupervised, ensemble methods), Deep Learning & Neural Networks (CNN, RNN, NLP), Generative AI & LLMs, and an end-to-end Capstone Project. See the full curriculum section above for week-by-week details.
Do you provide placement assistance after the Data Science course?
Yes, we provide comprehensive placement assistance including: resume building tailored for Data Science roles, mock interviews (technical + HR), direct referrals to our network of 73,000+ hiring partners, job alerts, and career counselling. Important: This is placement assistance, not a placement guarantee. Final job offers depend on your performance in interviews and market conditions. Read our disclaimer for details.
I have no technical background. Can I still join the Data Science course?
Absolutely. Our curriculum is designed for complete beginners. We dedicate the first 4 weeks entirely to Python programming basics — variables, loops, functions, OOP. Many of our most successful students came from non-tech backgrounds (commerce graduates, mechanical engineers, BPO professionals). The pace is gradual and we provide unlimited doubt clearing sessions.
What is the difference between Data Science, Data Analytics, and Machine Learning?
Data Analytics answers "what happened" — extracting insights from existing data using SQL, Excel, Power BI. Data Science answers "why did it happen and what will happen next" — using statistics and machine learning to build predictive models. Machine Learning is a subset of Data Science focused on building algorithms that learn from data. Our Data Science course covers all three areas, with deeper focus on ML/AI.
What certification do I get after completing the Data Science course?
Upon successful completion (75%+ attendance and clearing assessments), you receive the Livewire Master Certificate in Data Science with AI. Livewire is a recognized training brand operating since 2015. The certificate is verifiable online and accepted by hiring partners. Note that this is a training certificate, not equivalent to a university degree — see our disclaimer for details.
Which Python libraries will I learn for Data Science?
You'll master all industry-standard Python libraries for Data Science: NumPy (numerical computing), Pandas (data manipulation), Matplotlib & Seaborn (visualization), scikit-learn (machine learning), TensorFlow & Keras (deep learning), PyTorch (research-grade DL), SciPy (scientific computing), and OpenAI API for Generative AI. You'll also learn Jupyter Notebook and Git/GitHub for version control.
How many real-world projects will I work on?
You'll complete 15+ hands-on projects throughout the 6 months including: data scraping with Python, e-commerce database querying with SQL, sales analytics dashboard with Tableau, customer segmentation with clustering, fraud detection with classification, image classification with CNN, sentiment analyzer with NLP, and a final end-to-end Capstone Project that becomes your portfolio centerpiece for job interviews.
What is the average salary after completing a Data Science course?
Based on industry data (Naukri.com, LinkedIn 2024-25), entry-level Data Scientists in Chennai earn ₹4-6 LPA, with Mid-level (2-4 years) at ₹8-15 LPA and Senior roles at ₹18-35 LPA. Note: salary depends on your prior experience, project portfolio, interview performance, and the hiring company. Cognitec does not guarantee specific salary outcomes.
Where are Cognitec's training centers located?
We have four training centers: Anna Nagar (Chennai), Padi (Chennai), Velachery (Chennai), and Coimbatore. All centers have well-equipped labs, classroom infrastructure, and the same curriculum and trainer quality. You can choose the center closest to your home or office. For exact addresses and Google Maps directions, visit cognitec.in/contact-us.
Can I get a refund if I cancel after enrollment?
Yes, we have a transparent refund policy: 90% refund if cancelled 7+ days before batch start, 75% if 1-6 days before, 50% within 7 days of batch start (max 2 classes attended), no refund after 3+ classes attended. You can also opt for a free batch transfer instead. See our full Refund Policy for complete details.
What if I miss a class? Do you offer doubt clearing?
Yes. We provide unlimited doubt clearing sessions for all enrolled students. If you miss a class, you can: (1) attend the same topic with another batch, (2) attend dedicated weekend doubt-clearing sessions, or (3) book a 1-on-1 session with the trainer. We don't believe in leaving anyone behind.
How is Cognitec different from other Data Science institutes in Chennai?
Three key differentiators: (1) 100% classroom training — not pre-recorded videos like most online platforms; (2) Industry trainers with 20+ years experience — not freshers teaching freshers; (3) Livewire franchise heritage since 2015 — 90,000+ students trained across our network. Plus, our 6-month timeline gives proper depth for ML/Deep Learning — many competitors squeeze the same content into 3 months and skip critical concepts.
