About this course
For analysts who write pandas and still reach for a loop when the data gets awkward. You finish with one tidy table, a vectorized pipeline and a written record of each decision you made about the data on the way.

The tutor would not hand me the answer, which annoyed me for a week. It is also why I could do it alone in my interview last month.

The reviewed project got me the interview, and talking it through got me the job. I shared my screen on the call and took them through it.
Maya T.Analyst, logistics

Two courses in, I still froze at a blank screen. Here every lesson ends with something you write, and the tutor asks what you expect.

Too slow at the start for anyone who already writes code. It picks up in the second half, but I nearly gave up on it in the first week.
Amara N.Nurse, moving into data

I started without knowing what a CSV was. Ana never assumed I knew anything, never made me feel slow for asking, and answered every question I posted, even the ones I was embarrassed to ask. By week six I was using what I learned at work, and my manager has since moved me onto the reporting team, where I build the weekly figures for every ward.

Ana pointed at one step in my project and asked how many rows it should return. In five years of spreadsheets, I had never asked myself that.

Enrolling
What people ask before they enroll
A person answers anything this list does not. Ask us.
Enough of the basics to follow along without stopping to look things up. Lesson one is free, so open that first: if its practice set feels routine to you, you are ready for the rest of the course.
Nothing expires. 2 weeks at 4 hours a week is the pace the course was planned at, and at 2 hours it takes 4 weeks. The panel above works out a finish date for whatever pace you give it.
This one is self-paced only: at 2 weeks it would be over before a cohort found its rhythm. The discussion under each lesson is where the other learners are, and the instructor reads it.
The project itself, reviewed, and a line on your record that links to it. A guided project carries no certificate, because the finished work, with the review attached, is the thing you show an employer.
Yes, within 30 days of enrolling, from your account page and with no form to fill in or reason to give. Lesson one is free with the tutor, so most people know the course suits them before they pay.
Waypoint Plus is $29 a month and opens this course along with every other. At $29 this one costs about a month of it, so buy it on its own if it is the only course you mean to take this year.
Watch lesson one tonight. Decide in the morning.
It opens with the tutor beside it and the practice set under it, and asks for no card. The other 7 lessons are $29 once, or part of Plus.
