Falling behind after switching majors mid-semester

One more thought - One more angle: ask the department about prerequisite overrides or corequisites so you can take a later class while finishing the prereq which can save a semester. If you do withdraw from anything, confirm you still meet full-time/financial aid thresholds. A focused mini-mester or summer section is a low-risk way to knock out a single prereq. For this term, time-block the hardest class first and let everything else support that priority.

Good point - Nice. To make it even smoother predefine a tiny personal shorthand on the inside cover (WTS, s.t., wlog, bound, expand, factor, complete square) so you’re not inventing on the fly. When algebra flies, write the start and end line with a small blank in between and tag it with your reason code; you can backfill that gap later using the numbers. I’d also star the pivot line and note the quantifier shift or case split in words - those are the parts you’re most likely to forget, not the arithmetic.

Agree with you - Great advice. Two add‑ons: interleave similar topics during those retests (A, B, C then back to A) so you practice choosing the right method, and use successive relearning - cycle a missed item until you can recall it cleanly twice with a short gap, then park it. I also like a quick 2‑minute same‑day brain dump right after a block to catch fragile bits, then lean on the 1–3–7–14 spacing for lasting memory.

Use a structure-first template so you capture the logic, not every symbol. At the top of each new proof write Given:, Goal:, Strategy: in the margin, then number the major steps as 1, 2, 3 as the prof moves. In each step write a short trigger and result, for example "use Cauchy-Schwarz -> bound on norm" or "by induction step, P(k) -> P(k+1)", and skip algebra with a placeholder like [alg -> Eq. (3)]. Assign your own equation tags (1), (2), (3) to the board's key lines so your steps refer to them rather than re-copying and and circle the pivot line where the proof turns, like when existence becomes uniqueness. Keep a two-column page: left column holds the roadmap steps and equation tags, right column is empty during class for details you fill in later.
While the prof talks, aim to capture the flow verbs and reasons: define, assume, apply theorem X, substitute, conclude, and put a small square beside gaps you need to re-derive. Immediately after class, spend 15 minutes filling the squares, expanding one skipped algebra chunk per step and checking that each arrow you wrote is valid. Use consistent shorthand to stay fast, for example "wlog" for without loss of generality, "iff" for if and only if, and "dfn" for definition, plus one color for your paraphrase and another for questions. Concrete example: when they prove the derivative of x^x, you can write Given: y = x^x, Goal: y' = ?, Strategy: log-diff. Steps: (1) ln y = x ln x, [alg], (2) y'/y = ln x + 1, (3) y' = x^x(ln x + 1), and fill the [alg] later. If photos or recordings are allowed, grab a photo at each board reset and use it only to fill your right column, but the core method works with paper only.
What’s a simple way to remember things for a test without cramming

Everything is trying to sell you "memory hacks" with a 19.99 subscription and pastel UI. You don't need it. What works is short daily recall and spacing, which is miraculously free if you make your own cards. The cost is time and a little boredom.
I'm mad I learned this after paying for a course that mostly read slides back at me. Now I set a 10-minute timer, quiz myself from a tiny stack, and stop. If I miss a card twice, it goes to tomorrow; if I nail it, it waits a couple days. Library printer for a dozen index cards beats another subscription. If you need an app, use a free one with spaced intervals, but don't pay to procrastinate.

idk, one class first term, see vibes, then scale. For what it's worth, taking a few minutes to practice this in a calm setting usually helps it stick.
