Important Tips for Students and Competitive Exams

These tips from Telangana SSC syllabus and exams like SSC CGL/IELTS help score in preposition/negative structure questions:

• Tip 1: “Not by” focuses on past/future deadline failure (e.g., “not completed by 5 PM”). Use for time-bound tasks.
• Tip 2: “Not until” delays action to a later point (e.g., “not until 6 PM”). Ideal for sequence in narratives.
• Tip 3: In exams, swap “by/until” to test meaning—e.g., “Finish by Monday” (deadline) vs. “Finish until Monday” (incorrect).
• Tip 4: Avoid “not until by”—use one preposition. Common error in cloze tests.
• Tip 5: Practice with timers: Rewrite positives to negatives for speed in competitive papers.
