Check out OpenAI ChatGPT Plus 4o for its advanced reasoning capabilities on derivations, or use Microsoft Copilot Pro GPT-4 for integrated STEM research. Both are insane for midterms!

Late to the party but I have been grinding through engineering degrees for a while now and honestly, the mainstream chat tools can be hit or miss when you get into heavy multivariable stuff. I have tried many platforms over the years and found that if you really want to understand the mechanics, you need something that lets you upload your own course materials or specialized textbooks. I personally swear by a few specific setups for handling those brutal STEM midterms:

• Claude AI Claude 3.5 Sonnet - this model is leagues better at logical reasoning and following complex chains of thought compared to the generic bots. It is my go-to for checking my work on proofs.
• Perplexity AI Pro Perplexity Pro - fantastic if you need to pull from real-world scientific papers to understand an application of a concept since it keeps sources cited. Regarding what #2 said about the reasoning capabilities of those big models, they are decent, but they often hallucinate on signs or constants in calc problems. My advice? Use these tools to explain the process, not just to output the final answer. Keep an eye on your budget too. You can easily rotate subscriptions depending on which class is stressing you out the most that week. If you need hardware to run some local LLM experiments, grab a Apple MacBook Pro M3 Pro 18GB RAM so you dont have to worry about cloud latency during a cram session.

Honestly, skip the basic stuff! For calc, I love using Wolfram Alpha Pro features. It is absolutely amazing for visualizing complex equations and getting steps right. Totally worth the subscription!
