check_answer

Grades the user's choice and returns an explanation for EVERY option, including the ones they did not pick. On this exam two options are frequently defensible and only one is credited, so the reasons the wrong options lose are the part worth teaching.

examstring, required

Exam slug.

selectedarray, required

Option letters the user chose, e.g. ["B"] or ["B","D"].

question_idstring, required

The id from get_practice_question.

This tool isn't marked read-only, so it may change something on the server or in an account you connected.

I understand, run it anyway

get_practice_question

Returns one original practice question with its options and no answer key. Present it to the user and let them choose before calling check_answer. Pass every id already served in exclude_ids — this server is stateless and remembers nothing.

read-only

Argument	Type	Description
exam*	string	Exam slug from list_exams.
focus	string	Optional ordering by how everyone else answers these questions: "hardest" serves the highest crowd miss rates first, "traps" serves the questions most people get wrong the SAME way — a shared misconception rather than merely a hard question. Nothing is filtered out; questions with no crowd data simply come last.
domain	string	Optional domain id (e.g. "d3") to drill one area. Domain ids come from list_exams.
exclude_ids	array	Question ids already served in this session, so they are not repeated.

list_exams

The Claude certifications covered here, with exam codes, item counts, fees and the full domain list with published weights. Call this first to get valid exam slugs.

read-only

my_progress

Their recorded history for one exam, broken down by blueprint domain with the weakest first, plus how their misses compare with everyone else's on the same free-form questions. Call this at the start of a study session to decide what to drill, and after a run of questions to show what moved. It names the domain to pass to get_practice_question, and when their misses follow the crowd's favorite wrong answers it says to drill those with focus: "traps". Only a signed-in account has history; anonymous callers are told so rather than shown zeros.

read-only

exam*	string	Exam slug from list_exams.

  "type": "object",

open_study

Open or resume the study page for an exam, optionally focused on a domain or a sub-objective. Use this when someone asks to study rather than to be quizzed in chat: the page gives them a visible question they answer themselves, and once it is open a richer set of tools appears for reading and steering that screen. Returns the URL; a browser agent should navigate there.

read-only

Argument	Type	Description
exam*	string	Exam slug from list_exams.
domain	string	Optional blueprint domain, e.g. "d3".
sub_objective	string	Optional concept, e.g. "d1.5". Ids are per-exam.
