Excellent explanations and amount of course work for practice, the tests made good use of the examples and work given, I am satisfied with what I learned in this course and see it's real world usage.

This is an Awesome Course . The best thing About this Course is that It has weekly quizzes and Assignments as well as Practice Quizzes for particular Topics which helps in learning it more easily .

Good content but I wish the topics moved a little quicker. Seems like there is more hand holding than necessary.

All in all, this was a tough course, and the programming increased progressively as one moved on. Week 1 was OK, but I experienced a temporary hiccup in week 2 in the reading of the codon files; until I converted them to Strings. Even then the first file which contained only one DNA string gave its fair share of problems. In general, the section on Strings was pretty comprehensive. The programming was also pretty challenging. The section on debugging was OK, but I am at this stage still a little confused as to the amount and detail of information one is supposed to supply to someone else when you are experiencing a problem with your code. With the week 2 quiz I made a mistake than came back to haunt me in week 4; I did not read the question properly and from the outset my cgRatio method was not producing the correct answer. Eventually, after reading the specs for cgRatio again, I realised my mistake, could correct my code and get through the week 2 quiz! Week 3 on parsing, reading CSV files etc, the going was pretty good and I managed to complete the work covered in this section without too many problems. Week 4 on baby names; well, yes the mini Project was pretty extensive, with a lot of Methods being asked for and written. I found the small test files to be invaluable during testing. But the quiz contained a few curved balls. Method totalBirths does just that, and although in the specification it does say that it should also print the number of girls and boys names, and the total names in the file. Q1 and 2 tripped me up, I did not read them properly, and entered the total number of births for the girls and boys respectively. Questions 9 to 12 also resulted me in having to call a temporary halt, and write an additional method that looped over all the files from 1880 to 2014 in order to get the answers to those questions. Fortunately, method getRank came to the rescue here, doing all of the hard work!
This was a lot of work! I did "week 4" in one week, but only because I was already on leave and could focus on the mini project for the entire week. The entire course took me 6-7 weeks to complete.
I learned a lot. It was a good course, and very challenging. My greatest concern with the format you are using (80% or you don't move on - or you don't qualify), is that one can become "unstuck" as I did in week 2, but managed to get past that one.

Great course but be prepared for a pretty hefty workload.

Nice course, even though the 1st week assignments are not that good, but the rest of the course I enjoyed every single minute.

Week 2 is rough, quite frankly it's just a poorly implemented mess of frustration, but if you stick with it the second half is really solid.

Good flow, but the supporting document reference are very poor. Very hard to follow. Keep simple English difficult to understand in many Quiz.

Helpful in learning the basics of Java strings, classes, data types, etc. Semi-interesting projects and assignments and quizzes that test your code well.

Maybe, you should let us manipulate more the file, because the dukes library is doing much. But, in general this cours was interesting !!!

I have no prior programming experience beside the 1st course of this specialisation. It can be quite challenging at times but it's not impossible to finish.

Good challenges, good emphasis on relevant knowledge, but unreasoned instructions: had to rely more on myself and make my own programming exercises between some lectures to get comfortable with new material before moving on, as well as alterate some methods for better reuse during the exercises provided.
You can learn well from here, but pay attention, and dont afraid to exercise coding when you feel to

Pretty basic course if you have done any programming. It is pretty well designed. I don't recommend programming in bluej if you done some programming before. The environment is pain to use. Text editors all the way!!
