Now, let’s see whether you should enroll in the Udacity Data Engineer Nanodegree program or not-

Should You Enroll in Udacity Data Engineer Nanodegree?

Udacity Data Engineering Nanodegree is not a beginner-level program. This is the only intermediate-advanced data engineering course out there. This Nanodegree program requires the following skills before enrolling in the program-

Python–

If you are a beginner in Python, then don’t directly enroll in this program. To get 100% from Udacity Data Engineering Nanodegree Program, you need to know the following concepts-

• Strings, numbers, and variables; statements, operators, and expressions;
• Lists, tuples, and dictionaries; Conditions, loops;
• Procedures, objects, modules, and libraries;
• Troubleshooting and debugging; Research & documentation;
• Problem-solving; Algorithms and data structures

2. SQL-

Along with Python knowledge, you should be familiar with SQL programs such as Joins, Aggregations, Subqueries, Table definition, and manipulation (Create, Update, Insert, Alter).

If you meet the following prerequisites, then you can enroll in the Udacity Data Engineering Nanodegree. If not, first learn Python and SQL.

Now let’s see the price and duration of the Udacity Data Engineering Nanodegree program-

How Much Time and Money Do You Have to Spend on Udacity Data Engineering Nanodegree?

According to Udacity, the Udacity Data Engineering Nanodegree program will take 5 months to complete if you spend 5-10 hours per week.

And for 5 months they cost more than $800. But Udacity offers two options- One is either pay the complete amount upfront or you can pay monthly installments of $399/month.

So this is according to Udacity, but here I would like to tell you how you can complete the full Udacity Data Engineering Nanodegree program in less time.

Excited to know…How?

So, let’s see-

How to Complete the Udacity Data Engineering Nanodegree In Less Time?

To complete the Udacity Data Engineering Nanodegree program in less time, you need to manage your time productively.

You need to plan your day before and create a to-do list for each day. And you need to spend a good amount of time daily on the program.

According to Udacity, you need to spend 10 hours per week to complete the whole program in 5 months.

Right…?

That means, daily you need to spend 1.5 hours, but if you double the time and give daily 3 hours, then you can complete the whole Nanodegree program in less than 3 months.

For managing your time and avoiding any distractions, you can use the Pomodoro technique to increase your learning.

As I mentioned earlier, after each course, you have to work on a project. And each project has a set of rubrics. So before starting a section, I would suggest you just study the rubrics of the project. The rubrics will provide you with a rough idea about what topics and lectures are important for the project. So that you can make notes while watching these lectures.

And you can also implement the project phases after watching the related lecture. By doing this way, you can save time by watching one video two times. One at the time of learning and the second at the time of working on the project.

I hope these tips will help you to complete the Udacity Data Engineering Nanodegree program in less time. But you can also get Udacity Scholarship.

Do you want to know…How?

So, let me tell you how to get Udacity Scholarship.

How to Get Udacity Scholarship?

To apply for Udacity Scholarship, you need to go to their Scholarship page, which looks like that-

On this page, you have to find the scholarship for the program you want to enroll. If you found your Nanodegree program on the list, then you need to apply for the scholarship by filling out these details-

Student Reviews

I’ve learned, and applied, skills that I’d always wanted to get to grips with. After hearing so much about Relational and NoSQL databases, it’s satisfying to become confident building them with PostgreSQL and Apache Cassandra in only the first two projects!

Rob R.

My first project was very challenging to me but the reviewers and my mentor helped me constantly in improving my code and documentation and guided me well towards finishing the project. It was a great learning experience and looking forward to the other projects as well.

Nitheesha T.

The program is good, but you need to look at the dataset in the first project. I’m not completely new to ETL, but to have a requirement “Sparkify are interested in the songs their users are listening to”, then a dataset that doesn’t get near that must be confusing for real newbies.
