FAQ

Q. Is a free trial available?

Yes! Codetree offers a 7-day Free Trial when you sign up using a referral code. You can access all Codetrail content just by signing up—no credit card required. Once the trial period ends, your account will automatically switch to the Free Plan, so you can explore without any worry about being charged.

Q. I’m not sure which plan to choose.

If you know exactly which weaknesses to improve and have an exam coming up shortly, we recommend the Monthly Plan to help you stay focused.

However, as you immerse yourself in learning, you might become curious about the rest of the Codetree journey or even dream of bigger goals. Regardless of your current level, a 3-month journey is enough to spark a new challenge, and a longer commitment provides ample time to completely change your stage.
