🇬🇼 Guinea-Bissau → 🇺🇸 United States · Natural Sciences · 2026
Planning to study Natural Sciences in United States from Guinea-Bissau — perhaps as a scientist or researcher? Here's the TOEFL you'll need, the score range universities there look for, and how to confirm it on the new 1.0–6.0 scale.
TOEFL is the most widely accepted English test by US universities. Most ask roughly 80–100 on the retiring 0–120 scale (often 100+ for competitive programmes); on the new 1.0–6.0 scale that maps to about the upper-B2 to C1 range (~4.5–5.5). Confirm the figure your university lists — many are still updating.
Approximately 90% of US universities accept TOEFL, and it is the most widely accepted English test for US admission. Globally, TOEFL iBT is accepted by more than 13,000 universities and institutions across over 160 countries. Confirm the exact score your programme needs on its official admissions page.
Your overall TOEFL score is now the AVERAGE of the four sections (Reading, Listening, Speaking, Writing), each scored 1.0–6.0 in half-band steps — not the old 0–120 sum. The scale is CEFR-aligned.
The Natural Sciences requirement is set per programme (postgraduate often higher) — confirm the current figure on the university's official page. Many universities and visa authorities are still updating their thresholds during the 2026–2028 transition — confirm the current figure (and which scale, new 1–6 or old 0–120) on the official source before you rely on it.
Guinea-Bissau is Portuguese-speaking, so Portugal is the leading destination; regional applicants use Campus France; English-taught programmes need TOEFL.
