Lebanese Baccalaureate - General Sciences (GS)

It is a written, constructed-response examination: separate papers for mathematics, physics, chemistry and biology, plus an integrated scientific component. You write out solutions, derivations and justifications rather than selecting answers. The official body publishes the exact paper structure and instructions each year, so check its site before you plan revision.

Timing and the number of exercises vary by session and by subject, and the official authority publishes the current arrangements. Do not rely on numbers from older sessions or from other people. Download the current regulations and the most recent papers, and build your timed practice around what those documents actually say.

The content is standard final-year science, but the difficulty is in the writing: multi-step problems, proofs, and interpreting experimental data under time pressure. Students who lose marks usually do so through incomplete justification or skipped steps, not through unknown theory. Expect to practise full papers under time limits before the exam.

Retake and repeat-session rules are set by the official examining authority and can change between years. There is no single answer that applies to every candidate or session. Check the current regulations on the official site, or ask your school's administration, before you make decisions about a second attempt.

Passing thresholds, subject coefficients and any compensation rules are set officially and published by the examining authority. They are not fixed numbers you should assume from hearsay. Confirm the current rules on the official site, and ask your teachers how the coefficients affect the order in which you should prioritise subjects.

Start with mathematics, since it carries the heaviest weight and its methods feed physics and chemistry. Then physics and chemistry, which share mathematical tools. Keep biology on a steady weekly cycle because it rewards spaced recall. Leave the integrated scientific paper for the final phase, once the separate subjects are solid.

Answers without units, results stated without justification, graphs drawn without labelled axes, and chemistry equations left unbalanced. In biology, vague wording instead of precise terminology. In mathematics, skipping the reasoning between steps. Correctors award method marks, so write the solution as a readable argument, not just a final number.

Use them in two passes. First, untimed, to map which topics actually appear and how they are phrased. Then timed, under exam conditions, writing full solutions. Mark your own work against the official marking guidance where available, and keep an error log so repeated mistakes become visible before the exam.

All administrative details - registration deadlines, session dates, fees and required documents - are published by the official Lebanese examining authority and are updated each year. This page does not reproduce them. Consult the official site or your school's administration for the figures that apply to your session.
