Both practice arguments and all ten answer choices are AccessPrep-created practice items, not official LSAC questions. The court, the orchards and the student below are fictional. The role rules, error codes and stopping rule are teaching proposals, not tested findings. AccessPrep and Lovare share a founder, and Lovare offers paid LSAT instruction and admissions consulting.

When you miss a main conclusion question, write down why your answer looked right before you read the explanation. Then map the argument: give every claim one role (opposing view, background, premise, intermediate conclusion or main conclusion) and run a “because” test between any two claims that receive support. In the argument being analyzed, the main conclusion is the position the other claims are offered to establish; an intermediate conclusion also supports a further claim. The role of the claim you chose helps you investigate the step that failed. Turn that step into one repair check, test it on fresh questions, and move on after two clean transfers.

Who this is for

You missed a main conclusion question, and the explanation made sense afterward. That does not show you will find the conclusion next time. Success is three things in writing: the role of the claim you chose, the step that failed, and your results on fresh questions answered with the repair.

The blind-review guide covers committing to an answer before you check the key, and it tells you to “separate the conclusion from its support.” This lesson does that separation claim by claim, for arguments with more than one conclusion. LSAC lists “Recognizing the parts of an argument and their relationships” among the Logical Reasoning skills, and its October 26, 2026 announcement keeps the question types unchanged when the format changes in August 2027, so this method applies to either format.

Try the question before reading on

AccessPrep-created practice item, not an official LSAC question.

Court administrator: The county court plans to replace the printed self-help packets it gives to tenants in eviction cases with an online tool that guides them through the required forms. Tenant advocates object that tenants without home internet access will be shut out. But the court should proceed with the plan. Computers running the tool will be set up in the clerk’s office, where the packets are handed out now. And unlike the packets, the tool flags missing information before a form is filed. So tenants without home internet access would be better served by the tool than by the packets, not shut out.

Which one of the following most accurately expresses the main conclusion of the court administrator’s argument?

(A) Tenants without home internet access would be better served by the online tool than by the printed packets.

(B) If the printed packets are replaced by the online tool, tenants without home internet access will be shut out.

(C) The county court plans to replace the printed self-help packets it gives to tenants in eviction cases with an online tool.

(D) The court should go ahead with replacing the printed self-help packets for tenants in eviction cases with the online tool.

(E) The court should replace all of its printed self-help materials with online tools.

Commit to an answer and write one line on why. That line is what you will diagnose.

Give every claim one role

Number the claims, splitting compound sentences. Map support in the argument being analyzed, not every argument reported in the passage. These roles are a simplified review aid: a concession can also serve as a premise, so map its function rather than treating “admittedly” as decisive.

Claim X supports claim Y if “Y, because X” reads as the author’s own reasoning. When two claims both receive support, run this because test both ways: the one that supports the other is not the main conclusion. Signal words such as “But” and “So” show you where to look, but they do not decide roles.

Because test between claims 3 and 6: “The court should proceed with the plan, because tenants without home internet would be better served” is the administrator’s reasoning; the reverse is backward, since what the court should do is not evidence about what serves tenants. So claim 3 is the main conclusion, and (D) is credited.

Why each wrong answer fails

The failure, then the repair

Fictional illustration, not a real student’s record.

A student chose (A). Their note, written before checking the key: “Last sentence starts with ‘So’ and answers the advocates, so it’s the point.” Their first log entry, “Picked the intermediate conclusion. Slow down,” named the outcome, not the step, and gave them nothing to check. The repaired reasoning chain:

The error log below turns this chain into an exact error and a repair check.

Name the exact error from the role you chose

Ask which claim in the argument your answer comes from, and whether it keeps that claim’s scope. Read the table from the top and take the first row that fits.

Role codes (IC, PREM, BG, OPP) apply even if the scope also shifted, and mean your map needs repair. OVER and NARROW mean your map may have been right but your word comparison was not. The likely step is a hypothesis that your note from before the key helps you investigate: “this sounded most important” and “this came after ‘so’” are both IC misses with different repairs.

Keep the transfer attempt independent. Use transfer-question-only.md in the worksheet ZIP before opening the answer section below. Record your map, predicted conclusion and choice first. If you already saw the key, use this item for explanation practice and mark it familiar; it cannot count as a fresh transfer attempt.

Transfer question: same skill, different structure

AccessPrep-created practice item, not an official LSAC question. The valley, wasps and growers are invented, and the biology is simplified for the exercise. Cover the answer choices, write your role map, then uncover them.

Entomologist: The parasitic wasps released in the valley’s apple orchards last spring will not protect this year’s crop from codling moths. Some growers disagree, and they say that orchards where the wasps were released should not be sprayed this year. But most of the released wasps died during the February cold snap, so too few remain to breed a large summer generation. Besides, the wasps lay their eggs only in codling moth eggs laid after mid-June, by which time the first generation of moths has already damaged the fruit.

Which one of the following most accurately expresses the overall conclusion drawn in the entomologist’s argument?

(A) Most of the wasps released last spring died during the February cold snap.

(B) Orchards where the wasps were released should not be sprayed for codling moths this year.

(C) The wasps released last spring will not protect this year’s apple crop from codling moths.

(D) Too few of the wasps released last spring remain to breed a large summer generation.

(E) The wasps released last spring may not fully protect this year’s apple crop from codling moths.

Answer and explanation

Credited answer: (C). Split the third sentence at “so” to get five claims. Claim 1, the opening sentence, is the main conclusion and carries no signal word; claims 4 and 5 support it by separate routes. The because test settles 1 against 4: “The wasps will not protect this year’s crop, because too few remain to breed a large summer generation” is the entomologist’s reasoning, and the reverse is not.

Surface cues change between the examples; inspect the support relationship again.

Copy this error log

Use one entry per missed question. Before checking the key or reading an explanation, record field 1, your own answer in field 2, and your reason in field 3. Add the credited answer only after checking the key, then complete the map, error code and repair. The completed entry below is for the fictional court miss above; copy its form.

Make “clean” an observable record

Before checking the key, save three things: your predicted conclusion, one support arrow from a reason to that conclusion, and your reason for rejecting the strongest rival. After checking, mark whether the key or explanation exposed a missing link. A correct guess is shaky, and an answer remembered from an earlier review is familiar, not a fresh attempt. Keep a small reserve of unseen official questions; do not count repeated exposure as transfer.

When to move on: the stopping rule

Classify every transfer attempt:

A round is your transfer attempts for one logged error, on questions you have not seen. The orchard question can be your first attempt if you mapped it before reading its explanation. After that, use official main conclusion questions: LSAC’s practice page lists four full PrepTests free through LawHub (checked November 4, 2026). Take later attempts at your normal test pace. After each attempt, apply these in order and take the first that fits:

1. Two clean attempts in this round: move on. Close the log entry, and reopen it if the same code shows up again.

   
   

2. Two misses in this round: switch. Stop answering full questions for this error and drill the repair step alone: for a role error, map arguments with the choices covered and check your main conclusion against the key; for a matching error, write the conclusion’s scope and strength words before comparing any choice. Start a new round next session.

   
   

3. Four attempts in this round: switch, as in rule 2, rather than use up more fresh questions.

   
   

4. Otherwise: one more fresh attempt.

   
   

What this rule cannot tell you. These thresholds are editorial practice limits, not validated cut-offs. “Clean” rests on your own honest record, since only you know whether you mapped first or guessed between two; when unsure, log the attempt as shaky. Two clean results do not establish mastery or prove that the repair caused improvement. That is why rule 1 reopens the entry when the code returns.

Turn your next missed question into a finished review.

Free first step: log your most recent missed main conclusion question in the form of the completed court entry above, then start a round on fresh questions. For a broader weekly plan, the free LSAT Study-Plan Check asks five questions and gives you a seven-day plan with no email required.

Optional paid path: if several codes keep appearing in your log, or one code ends two rounds in a switch, you can ask a prospective tutor to examine a recorded example of your reasoning and explain what they would test next. Current one-on-one LSAT programs are offered through Lovare Institut, which shares a founder with AccessPrep. You can see current Lovare LSAT programs or contact AccessPrep to discuss your plan.
