Checklist to Avoid Course Selection Mistakes

AI courses aren't cheap investments. To avoid regrets, check this list before signing up.

Curriculum Check

  • Does it cover the AI tools you want to learn (ChatGPT, Claude, Midjourney, etc.)?
  • Is the curriculum updated for recent AI developments (2024 onwards)?
  • Are there practical project assignments (not just theory)?
  • Does the estimated study time fit your lifestyle?

Support System Check

  • Q&A methods (chat, video call, forums) and available hours
  • Instructor credentials and expertise (do they have real AI work experience?)
  • Post-completion support period (can you ask questions after finishing?)
  • Community or Slack group for student networking

Cost & Contract Check

  • Does total cost include materials and enrollment fees (any hidden costs)?
  • Payment plan interest rates and fees
  • Refund guarantee and cooling-off policy terms
  • Any government subsidies or tax benefits available

Warning: Be cautious of claims like "guaranteed earnings" or "quick ROI." Skill acquisition varies by individual and income is never guaranteed.

Priority of Skills to Learn in AI Courses

To acquire skills efficiently with limited time, understand the priority of skills to learn.

Priority 1: Prompt Engineering

The skill of writing effective prompts (instructions) for AI. This is the foundation of all AI use. Whether ChatGPT, Claude, or image generation AI, good prompts produce good results.

Learning estimate: Can master basics in 2-4 weeks

Priority 2: Deep Understanding of Specific AI Tools

Understanding one tool deeply - ChatGPT, Claude, Midjourney, etc. - is crucial. Mastering one tool tends to be more useful for side hustles than knowing many tools superficially.

Learning estimate: Can reach professional level in 4-8 weeks

Priority 3: Business Automation Skills

Skills to automate daily tasks using AI. Zapier integration, GPT API usage, combining with no-code tools, etc. Useful not just for side hustles but also for your main job.

Learning estimate: Can do basic automation in 4-6 weeks

Priority 4: AI Development & Programming

Python, API development, machine learning, etc. For those aiming for engineering careers. Opens possibilities for more specialized, higher-paying projects, but takes longer to learn.

Learning estimate: Can reach professional level in 3-6 months

For Those Who Want to Learn Free First

"I'm nervous about expensive courses..." - If that's you, starting with free learning options is also valid.

1. Free Consultations from Schools

Most schools offer free consultations. Just hearing about the content is educational.

2. YouTube & Free Articles

There's plenty of free information on how to use ChatGPT. Though systematic learning may be challenging.

3. Google's Free AI Courses

Introductory levels are free. Good for checking if AI is right for you first.

Frequently Asked Questions (FAQ)

Q. Will taking an AI course really help me earn through side hustles?

A. Skill acquisition and income aren't directly linked. Courses give you a foundation to try side hustles, but actually earning requires finding jobs and doing business development yourself. However, having practical skills does increase your chances of landing jobs. A realistic goal is aiming for a few hundred dollars monthly income 3-6 months after completing the course.

Q. Can I take an AI course while working full-time?

A. Many AI courses are fully online and self-paced. If you can secure about 10-15 hours per week, you can take courses while working. Many students study 1 hour on weekdays and catch up on weekends. If unsure, consult during a free trial about whether it fits your schedule.

Q. Can I succeed without programming experience?

A. Yes, many AI courses are designed for beginners. Generative AI tools like ChatGPT and Midjourney can be used without programming knowledge. However, if aiming for an AI engineer career, you'll need to learn programming skills like Python alongside using ChatGPT and Claude. Choose a course that matches your goals.

Q. Course vs self-study - which is recommended?

A. It depends on your goals and situation. Self-study's advantage is low cost; courses' advantage is systematic learning with lower dropout rates. Courses are recommended if you want "to definitely acquire skills in a short time," "need a place to ask questions," or "want to learn with peers." On the other hand, if you "have plenty of time," "are good at self-management," or "want to minimize costs," self-study can work.

Q. What if I want to quit midway?

A. Policies vary by school. Some offer partial refund guarantees, others allow full refunds within a cooling-off period. Before signing up, always check "mid-course cancellation policy" and "refund conditions." Many platforms also offer cooling-off periods where you can get a full refund within a certain number of days.
