Final Notes
Start free, and only pay when it really matters. Most STEM majors can complete entire courses with no-cost tools. When the time comes to upgrade, student discounts and campus licenses stretch your budget further than you might expect.
Keep your GitHub profile polished and maintain a clean LaTeX rรฉsumรฉ on Overleaf, and you’ll already have a professional edge by the time internships roll around.
A similar question often arises in technical education – can a trade school degree lead to a long-term career? In many industries, the answer is yes, provided students pair hands-on training with tools that showcase their skills effectively.
The best toolkit is the one you actually use consistently. Pick your essentials, layer in upgrades only when you need them, and let the resources above carry you from intro courses all the way to senior projects.
