Oh yeah, and use tools like WolframAlpha to check your work and explore problems in more depth (like visualizing functions, seeing alternate forms). Get the app and use the solution explainer thing—essential for e.g. solving integrals. It might be worthwhile to learn to solve and verify problems using some sort of (mathematical) programming language or a CAS. Could be anything, but something like SageMath comes to mind. Honestly, even Excel is pretty good for this. Being able to do simple things plot functions, verify work by plugging in values, simulate random numbers, etc. goes a long way. Developing this skills becomes even more useful (essential) when you’re at the college level and beyond.
