🇧🇩 Bangladesh: GST Cluster & HSC Grade (GPA 5.0) Evaluator
Compute the official Guccho (GST) merit score used by the 24-university unified public cluster: MCQ test (100) + SSC GPA × 2 + HSC GPA × 2 = total out of 120.
GST Merit Score
How the GST (Guccho) Merit Score Works
The unified 24-university cluster. The Guccho or General, Science & Technology (GST) admission test is a single national entrance exam shared by 24 public universities in Bangladesh. One test, one merit score, three streams: Unit A (Science), Unit B (Humanities) and Unit C (Business / Commerce). Candidates apply to individual universities only after their merit position is published from the central pool.
The 120-mark merit formula. The official circular fixes a single national arithmetic: Merit Score = (MCQ correct − 0.25 × MCQ wrong) + (SSC GPA × 2) + (HSC GPA × 2). The MCQ paper is 100 questions in 60 minutes, +1 for each correct, −0.25 for each wrong, no penalty for blanks. The SSC and HSC GPA bonuses cap at 10 each (5.00 GPA × 2), giving a total ceiling of 120.
Triple-gate eligibility lock. A high merit score does not guarantee a place. GST enforces three independent floors that all must clear: (a) the unit-specific minimum GPA in both SSC and HSC individually (3.50 each for Unit A, 3.00 each for Units B and C, including the 4th subject), (b) the unit-specific minimum combined SSC + HSC GPA (7.00 for A, 6.00 for B, 6.50 for C), and (c) the MCQ pass mark of 30. This calculator surfaces any failed gate even when the headline merit score is strong, so weak GPAs cannot produce a false "eligible" signal.
The regulatory trap. Many informal calculators only sum the GPAs (e.g. SSC 4.5 + HSC 4.5 = 9) without multiplying by 2, or apply the −0.25 negative marking only to the MCQ subtotal after the bonus is added. Both errors inflate the result by several marks and quietly mis-rank candidates. This tool computes the MCQ net first, then adds the GPA bonus separately, exactly as the GST circular defines.
