No requirements are needed to learn R. The only knowledge that needed to learn R is basic statistical knowledge.
No you cannot enroll for individual skill sets within a defined course on teleuniv.
Most learners are able to complete the Specialization in about 3 months.
We recommend taking the courses in the order presented, as each subsequent course will build on material from previous courses.
This specialization will unlock great career opportunities as a Hadoop developer. Become a Hadoop expert by learning concepts like Pig, Hive, Flume and Sqoop. Get industry-ready with some of the best Big Data projects and real-life use-cases.
We have limited number of participants in a live session to maintain the Quality Standards, hence, participation in a live class without enrollment is not possible. However, we can create a demo login for one demo session.
You can pay by Credit Card, Debit Card or Net Banking from all the leading banks. We use a Payment Gateway.
Teleuniv is associated with Keshav Memorial Institute of Technology, one among the top performing colleges in Hyderabad and hence lot of recruitment firms contacts us for our students profiles from time to time. Since there is a big demand for this skill, we help our certified students get connected to prospective employers. Having said that, please understand that we don't guarantee any placements however if you go through the course diligently and complete the assignments and exercises you will have a very good chance of getting a job.
