Here is your question -

Problem:

To complete this exercise connect to your Atlas cluster using the in-browser IDE space at the end of this chapter.

How many documents in the sample_training.zips collection have fewer than 1000 people listed in the pop field?

Copy/paste the exact numeric value (without double quotes) of the result that you get into the response field.

I didn't alter anything but still I got wrong answer from the sample_training DB.

Atlas atlas-3n88ij-shard-0 [primary] sample_training> db.zips.find({ "pop": { "$lt": 1000 }}).count()
8062

Hi,

M100: MongoDB for SQL Pros is a great course. I found it very useful in translating my SQL knowledge over to Mongodb.

I want to report two grammatically improvements:

1. Chapter 1: Read/Writes Operation Guarantees quiz - the questions say 'which one' but then below says check all answers that applies. I only checked one answer to begin with but their were multiple correct answers. See screenshot attached.

2. Chapter 2: Embedding vs Referencing quiz 2: a few grammatical improvements as in the screenshot attached.

Nothing major, it was great course!

1) Detailed explanation contradicts itself. First bullet states: "When using an index for filtering and sorting the query must include equality conditions on all the prefix keys that precede the sort keys." However, third bullet states: "Yes, while this query fails to use equality on the "address. state" field of the index prefix, it uses the same field for sorting."

2) Detailed explanation contradicts order requirement as described in lessons. Last bullet states: "The order of the fields in the query predicate does not matter." But lessons say that that order does matter.

Time index 04:33

The slide changes from A to B (see attached screenshots). Obviously, B is correct, but the use case "Find all nodes that are under Z" is not even discussed. This needs to be fixed.

In M121 course, instructor said to open terminal and connect to cluster but they did not tell how to open mongo shell from command prompt since we are new to mongo db it was painful to search in google and figure out. More details for basic necessary things would be appreciated.

There needs to be a solution to install mflix properly... I could do it... very disappointed...

Many videos in course M103 uses hand/finger to point to a particular line or command. This is very coarse and difficult to follow/locate exact word or line to look at. Instead of using finger/hand, use some kind of highlighter (yellow background or color border) on the intended line or command

Course list pages and actual courses are, unfortunately, decoupled.

I learned today that the two pages are not coupled to each other.

While on the courses listing page, I clicked on M220P course hoping it would take me to my "already completed" course page.

Instead, it just created another course to go for the next 60 days.

You ask for personal data on both the testimonial and the group at the end of each survey. We are not allowed to provide feedback by corporate. Having the name and email link is worrisome. If a person selects no you need to not ask for that data. It violates PII when No is selected.

I would like to have some kind of learning path in the University. From beginner to advanced where we can have courses listed and our progress clearly viewable.

It should be easy to see where the path split (mongo for node, mongo for .NET etc) so we can go back to the right point in the path if we first want's to do the node path and then jump back and do the .NET path (if there is a .NET patch... lol)

Any coupons for Certification will help like for AWS we have

Please use some kind of noise filter in the university videos to remove those discusting breath and chewing sounds.

Instead of having the in-browser IDE unusable for small screen devices, it would be a good idea to have an option to open it in a separate window, or some other solution.

Please notify members via a text when their paid exam is lapsing. My emails went to junk folder and I missed rescheduling and now I think I am gonna lose that 150 dollars.

I have almost completed a course but when I logged in again, it tells me that I have stopped at chapter 4 (out of 6). This is annoying and demotivating. It has happened multiple times.

was working at atlas, but i failed test?

Current content on : https://university.mongodb.com/exam/guide has some links not working and sometimes documents on docs.mongodb.com not having content as listed or discussed in videos. (Example sort with ranges and index order)

Request updating study content ensuring all video links are working with latest content.

Hi, MongoDB University I have noticed that the quality of course completion certificate is very poor. Even it is in "jpeg" format. Please provide it in "pdf" format.

This was a detailed course, with required information, assignments and labs. And help everyone to understand Security related things.
