About this course
Each idea starts as a simulation you run in the browser, and the formula arrives last, if it arrives at all. It suits analysts who report test results every week and would struggle to defend one in front of a skeptical manager.

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. Ibrahim 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.

Ibrahim 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.
No. The first module starts from nothing, and the tutor in each lesson answers the questions a first-timer asks, however basic they feel. What you need is 4 hours a week and a browser.
Nothing expires. 5 weeks at 4 hours a week is the pace the course was planned at, and at 2 hours it takes 10 weeks. The panel above works out a finish date for whatever pace you give it.
A start date, a finish date and a live review of the week's work every Thursday, with the same 30 people from the first week to the last. The lessons and the tutor are the ones the self-paced track gets.
A certificate from the school that made the course, and the project the instructor's team reviewed. Each comes with a link that anyone, an employer included, can open and check in a few seconds.
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 $49 this one costs about 2 months 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 12 lessons are $49 once, or part of Plus.
