Stanford CS224N and MIT 6.S191 are world-class — and brutal for unprepared learners. These focused prep courses close the prerequisite gap in a single weekend, give you a verifiable readiness certificate, and shave $50–$100 off the full CLLME diploma if you decide to keep going.
Most learners watch CS224N lecture 1, hit lecture 4, and quietly drop out. The lectures don't fail — the prep does. We fix that.
A focused weekend, not a semester
12–20 hours, no fluff. Just the math, Python, and intuition the official course assumes you already have.
A real on-ramp
Complete the prep, get a verifiable certificate, and apply your work toward Module 1 of our full CLLME diploma.

Pre-Stanford CS224N Prep
The exact math, Python, and ML fundamentals you need to keep up with Stanford's flagship NLP course on day one.
~12 hours7 modulesCertificate
Why this exists
CS224N assumes fluency in calculus, linear algebra, probability, Python/NumPy, and PyTorch — plus a working mental model of feed-forward and recurrent networks. Most self-learners watch lecture 1, hit lecture 4, and drop out. This course closes that gap in a focused weekend.
You will be able to
Read and derive the gradient of any feed-forward layer by hand
Implement softmax, cross-entropy, and backprop in pure NumPy
Use PyTorch tensors, autograd, and Modules without copy-paste
Explain word2vec, GloVe, and contextual embeddings in plain English
Includes
Lifetime access to all 7 modules + the capstone rubric
Get bootcamp-ready: the Python, math, and intuition you need to keep up with MIT's intensive 1-week Deep Learning Bootcamp.
~20 hours8 modulesCertificate
Why this exists
6.S191 compresses a semester of deep learning into one week of lectures and labs. The lectures are world-class — but the labs assume you already write Python, understand gradient descent, and have used TensorFlow or PyTorch at least once. This course gets you there.
You will be able to
Be able to follow every line of code in the 6.S191 lab notebooks
Train and debug a CNN, RNN, and small transformer end-to-end
Diagnose underfitting vs overfitting from training curves
Reproduce a paper's headline result from its abstract
Includes
Lifetime access to all 8 modules + the capstone rubric
Skip the prep and go straight to the full Certified LLM Engineer diploma — 12 modules, capstone, final exam, verifiable credential. Early enrollment locked at $49.
