Mastering CS Shouldn't Take a 4-Year Degree
The traditional path to computer science knowledge is slow, expensive, and often disconnected from what employers actually need.
CS Degree Barrier
Traditional degrees take 3-4 years and cost £27,000+, but the core concepts can be learned faster.
Interview Anxiety
Technical interviews at top companies require deep knowledge of algorithms and data structures most courses skip.
Theory vs Practice Gap
Many resources teach syntax without explaining why algorithms work or how to analyze efficiency.
Foundation Gaps
Self-taught developers often struggle with theoretical concepts that senior roles require.
There has to be a better way to become job-ready in computer science
