Build a study plan I can actually stick to

Build me a study plan.

What I am learning or preparing for: {{goal}}
Deadline or exam date: {{deadline}}
Hours I can realistically study per week: {{hours_per_week}}
Where I am starting from: {{current_level}}
Materials I have (books, courses, past papers): none yet
How I learn best, and what has not worked before: not sure

Build the plan like this:
1. Break the subject into its main topics. Mark which carry the most weight for my goal and which depend on others, so I learn them in the right order.
2. Check the numbers honestly: is the time I have enough? If not, say so and tell me what to prioritize and what to drop.
3. Lay out a week-by-week schedule. For each week: the topics, what to do (read, practice, review), and what I should be able to do by the end of it.
4. Build in what makes learning stick:
   - Practice that makes me retrieve things from memory, such as problems, self-testing, or explaining aloud. This should take more time than re-reading.
   - Spaced review of earlier topics, scheduled in, not left to chance.
   - Full practice tests or realistic projects in the final stretch.
5. Leave one catch-up session per week unassigned. Plans without slack fail.
6. Add a checkpoint every two weeks: a specific way to test myself, and what to change if I am behind.

Then give me:
- A typical single study session, minute by minute.
- The three most common ways people fail at this particular goal, and how this plan avoids them.

Rules:
- Size everything to the hours I gave. Do not assume I will find more.
- Be specific: "do 20 practice questions on topic X", not "review topic X".
- If you recommend resources, describe the type to look for. Do not invent specific titles or links.

Still to fill in: goal, deadline, hours_per_week, current_level
