Hiya! Lines and planes can be complex, can't they? On today's test we'll start with a standard on basics of vectors and the dot/cross products, equations of lines and planes and simultaneous equations. Obviously, HK is making an appearance here as the exams have  really good  simultaneous equations questions.  The actual test isn't gonna be this easy lmao Standard 2 is a time crunch.  Budget your time accordingly - if you're after that 7, you gotta speed up at the other standards.  If you're looking for more personalised support, don't hesitate to reach out and complete the form !

Hiya! The Survival Papers made a comeback! In the run up to finals, I'll be posting Survival Papers biweekly. These papers follow the same content as the Survival Guide , intended to be more accessible than the Booster Papers and the mock exams, with the main purpose of helping students securing a 5 on their externals. This test covers various topics from the entire course. There's a question on sectors, sequences and distributions. 7 questions, 50 marks, 50 minutes, with a heavier emphasis in section A where many students get more of their marks from. Mark your work using the MS and use the Scoring Guide to track your progress.

Hiya! Welcome to another unit test on sequences and series. General sequences/series, arithmetic and geometric series. (The first standard is not officially part of the course - except the sigma notation - but it builds the foundation for sequences and series at the end of the course and in uni.)    Three standards, the usual time crunch applies. No calc. If you're looking for more personalised support, don't hesitate to reach out and complete the form ! I'm @adventurousandrew on Discord.   AAHL: AAHL MS: AASL: AASL MS: Andrew
