This is an explanation of the 6 doors in Bowser's Castle in the Super Mario RPG Remake. It also includes information on the courses of the Mario RPG 6 doors and recommended courses, so please use it as a reference.
Recommended Courses
Both Battle Courses are Recommended

For the battle courses, you just need to repeat battles without thinking too hard. Also, since you can get Bowser's and Geno's pre-clear strongest weapons, the Drill Claw and Star Gun, be sure to clear them.
Get Mallow's Weapon in the Action Course
In the course where the first area involves jumping on blocks, you can get Mallow's pre-clear strongest equipment, the Sonic Cymbal. There is no other way to obtain it, so be sure to get it here.
Puzzle Courses are Less Recommended
Puzzle courses are difficult and the only item you can get is "Rock Candy", so they are less recommended.

Action Courses
Courses Requiring Action Skills

Action courses are courses where you advance by using Mario's unique actions like jumping and riding cannonballs. If you fail, you will lose coins, so be careful about the number of coins you have left.
Action Course 1. Walkthrough Video
Invisible Floors Become Visible When You Jump
One of the action courses features invisible floors, which briefly become visible when Mario jumps. Proceed while jumping to avoid falling into the magma.
No Need to Force Getting the Super Slap Glove
In the invisible floor course, you can get Peach's weapon, the Super Slap Glove. However, the Frying Pan obtainable in Booster Hill is stronger, so there's no need to force yourself to get it.

Points to Note for the Ball Riding Course
In the second area of Action Course 2, you need to ride a ball and avoid enemies. Be careful as the input direction is opposite to the direction of movement.

Puzzle Courses
Courses Where You Solve Problems

Puzzle courses are courses that you clear by solving problems or counting things. They require a lot of thinking but are interesting courses.
Quiz

A total of 12 questions are asked, and you can proceed if you answer 8 correctly. The questions are based on the content of your adventure so far and are randomized each time you enter.
Barrel Counting

A game where you count the arranged barrels and answer. There is a time limit, but count calmly and answer.
Deduction Problem

A game where you guess the triathlon rankings based on the testimonies of 4 people. It's a word problem, so read the lines of the 4 people carefully and find the answer.
Coin Grab

A game where you lose if you take the 21st of 21 coins. You can win by being mindful of multiples of 5 when taking coins.
Magical Switch

You can clear this by turning all switches on. Pressing one switch turns off the surrounding switches, so think about which switch to press as you proceed.
Ball Solitaire

A game where you make balls disappear by hitting them with other balls. You clear it if you can make all of them disappear, but if there are no more balls you can make disappear, you lose at that point.
What are the 6 Doors?
Courses in Bowser's Castle

The 6 Doors are doors leading to six courses that appear in the middle of Bowser's Castle. There are three types: Battle Courses, Action Courses, and Puzzle Courses. Which course you get is random, so you won't know until you enter.
Need to Clear 4 Doors
You cannot proceed unless you clear 4 of the 6 doors. If you choose a course you are not good at, you can return to the front of the doors by intentionally failing or by giving up with the - button.
Re-challengeable After Clearing

After clearing Bowser's Castle, you can re-challenge by coming to the door room again, and you can also go directly to the door room from the map. However, the inside of the doors remains random, and treasure chests once taken do not respawn, so there is no point in entering cleared areas.
