MUST — Critical Path

6 Tasks • ~10.0h

Non-negotiable core curriculum

DSA (Java) 2 tasks

DSA Arrays Medium I 3 problems LC #53

Two Sum, Sort an array of 0s-1s-2s (Dutch National Flag), Majority Element (Moore's Voting Algorithm). TUF+ A2Z Step 3.2 Includes Kadane's Algorithm (Maximum Subarray, LC #53).

3.0h

DSA DSA Transfer: No-Hint Timed Medium Set (Kadane & Subarrays) 2 problems LC #

Sit 2 unseen Medium problems you have never attempted (pick from the LeetCode topic tag, NeetCode “similar questions” or a company list; never a problem named in any learning task), at least 72 h after the learning task — move the set to the first half of next week if needed. Format: 25 min per problem (35 min for a Hard), including 5 min for edge cases and a dry run; no hints, no AI. Pass bar: ≥ 1/2 solved inside the time box; on a miss, log the miss reason in the Journal and re-sit a fresh pair within 7 days.

1.5h

Core CS (OOPs) 1 tasks

OOPS Abstraction & Interfaces

Abstract classes vs interfaces, default and static methods in interfaces, multiple interface inheritance in Java. TUF+ OOPs

1.5h

Core CS (Linux & Git) 1 tasks

GIT MIT Missing Semester: The Shell & CLI

Terminal navigation, bash syntax, pipes and redirects (|, >, <), process management (ps, kill), environment variables. Architecture §6.4

2.0h

Aptitude 1 tasks

APT Aptitude Decision Task: Audit Target-40 OA Formats

Using the Target-40 list, record whether each company uses MCQ aptitude, coding-only or mixed OAs. If ≥ 30 % of targets use MCQs, promote Quant M3–M5/Logical from SHOULD to MUST; otherwise keep them SHOULD. Why: avoids spending hours on aptitude that your targets never test.

1.0h

Recruiting Pipeline 1 tasks

PIPELINE Alumni & Senior Map

List ≥ 30 TSEC alumni/seniors working at Target-40 companies (LinkedIn, college alumni group); record company, role, batch and a shared hook. Why: referrals convert far better than cold applications.
