Any good mnemonics?

Has anyone come up with a foolproof method of retrieving the following in the exam?
FCFF = NI + Dep + [Int x (1 — tax rate)] — FCInv - WCInv
FCFF = [EBIT x (1 - tax rate)] + Dep - FCInv — Wcinv
FCFF = [EBITDA x (1 - tax rate)] + (Dep x tax rate) - FCInv - WCInv
FCFF = CFO + [Int x (1 - tax rate)] - FCInv
FCFE = FCFF — [Int x (1 — tax rate)] + Net borrowing
FCFE = NI + Dep — FCInv — Wclnv + Net borrowing
FCFE NI — [(1 — DR) x (FCInv— Dep)] - [(1 - DR) x WCInv]
They all make sense and look trivial but given a page of P&L and BS data it is very easy to omit or double account a component. So how do you remember all thes other than by brute memory?

I memorize, but spend time streamlining, cleaning up, re-ordering, so my brain doesn’t have to do a lot of work.
Net income

• FCFF = NI + NCC - FCinv - WCinv + int(1-t)
• FCFe = NI + NCC - FCinv - WCinv + net borrowing

CFO

• FCFF = CFO - FCinv + int(1-t)
• FCFe = CFO - FCinv + net borrowing

EBIT vs EBITDA

• FCFF = EBIT(1-t) + Dep - FCInv - WCInv
• FCFF = EBITDA(1-t) + Dep(t) - FCInv - WCInv

That is actually quite neat. Can you please open brackets for Net Borrowing?
